Destroying Syrian Chemical Stockpiles Won't be Easy

This article originally appeared in The Daily Beast on 6 September 2013.

It is now clear that the Syrian government used sarin nerve gas to attack suspected rebel forces in Damascus on August 21. There is no doubt that the “red line” was breached. With the American public delivering a clear consensus against committing ground forces, the Obama administration will almost certainly limit any intervention to remote attacks. In the best circumstances, destroying chemical weapons is a dangerous and intensive task, but trying to destroy them from the air without spreading their deadly agents makes it even more difficult.

Drawing from my experience serving 9 years in chemical, biological, radiological, and nuclear defense (CBRND) for the U.S. Army, here is a rundown of the options available for destroying chemical weapons with a look at the feasibility of different methods and the complications that each entails.

An air campaign could focus on eliminating chemical munitions, military chemical units, chemical weapons production facilities, any or all of the above. The first step is to identify the targets and fix their locations. Since the first mentions of chemical weapons use by the Assad regime in July 2012, U.S. intelligence has been tracking the movements of Syria’s chemical assets. There is a ready supply of human intelligence from rebel forces and refugees, a steady stream of signals intercepts from Syrian government forces, and near constant visual surveillance using aerial imagery platforms. Social media and news reports from inside Syria also provide open-source intelligence.

Syria is reported to have one of the largest stockpiles of chemical weapons in the world. Locating all of these munitions, even with the best intelligence available, will not be easy. Syria is also known to store chemical agents in“binary” form, where two components of the chemical agent are stored separately and only mixed before being loaded into munitions. This makes transport safer and simpler but can vastly expand the number of targets that need to be located and destroyed and makes them easier to conceal.

Syria’s chemical weapons-production facilities are reported to be located near major cities such as Aleppo, Damascus, and Homs, while munitions are stored at as many as 50 different sites. As the U.S. prepares for an attack, the regime is likely spreading munitions across cities throughout the country, making detection more difficult, necessitating more strikes, and increasing the likelihood of civilian casualties.

Some intelligence reports indicate that the Assad regime lacks the ability to produce certain necessary precursor ingredients, but Syria stockpiled chemicals from European suppliers before export controls became effective. It also doesn’t take much to create many of the chemical agents used; they can be produced by anyone with an advanced chemistry degree given a moderately equipped refinement facility. Targeting Syria’s production facilities is possible, but will be difficult. Tracking movements of Syrian military chemical units and weapons platforms capable of firing chemical munitions would be an easier task.

The hardest part comes after the munitions are located. Once the targets are acquired they must be destroyed without releasing the deadly chemical agents— it’s possible but a bit like bombing a paint factory at long range and expecting not to have any splatter.

Syrian chemical units and their launchers can be targeted using airstrikes, drones, or cruise missiles launched from naval vessels. However, given the likelihood that the Syrians have intentionally moved these weapons systems into populated areas, even precise strikes on them could lead to civilian casualties. On a larger scale, there is also the danger that an attack on launchers loaded with chemical munitions could spread toxic substances as far as Lebanon, Israel, and Jordan or into the Mediterranean Sea.

America must face the possibility that in carrying out attacks to prevent the Assad regime's use of chemical weapons it risks unleashing those deadly agents on a civilian population.

Other than weapon systems and facilities, Syrian soldiers working in chemical units are another likely target for attack. The troops in these units are usually outfitted in identifiable protective gear for their own safety, a clear indicator of the presence of chemical agents and their impending use. But attacking these soldiers presents a similar set of problems—their likely proximity to chemical weapons means that targeting them risks hitting the munitions they are guarding or operating and releasing them into nearby populations.

The care America takes in eliminating its own chemical weapons reflects how dangerous the process is, even when it’s done in a safe and controlled environment. Since 1986, the protocol has been to incinerate the agent at temperatures above 2,000 degrees Fahrenheit or to neutralize it using hot water and a caustic compound. After the destructive phase, the next step involves extensive monitoring and testing of air, water, and soil to ensure no residual release.

Simply dropping a conventional bomb on an ammo dump is not a solution. Besides the initial deadly effect of dispersing chemical agents, their release into air, soil, and water can have severe health effects for years down the road.

A chemical rocket or artillery round does not explode like conventional munitions. They contain a propellant to get the munitions on target and only enough explosive to rupture the round and release their agent, either bursting in the air above a target or upon hitting the ground. This is why there were several rockets found semi-intact after the August 21 attack on Ghutah which were subsequently sampled by U.N. investigators.

The U.S. Defense Threat Reduction Agency has conducted extensive research into anti-chemical strike options. One weapon they have studied is the non-explosive CBU-107 “PAW” which releases 3,700 extremely dense metal rods into a high-altitude free fall that acts like thousands of daggers, penetrating and shredding a target without the use of explosives. This weapon is less likely to cause an explosion at production facilities but it will rupture munitions, releasing their chemical agents and making casualties of anyone in the vicinity.

Thermobaric explosive weapons, like the BLU-119/B “CrashPad” are another option. Thermobaric explosives, essentially the most powerful non-nuclear devices in the U.S. arsenal, work by sucking in all the oxygen in the blast radius and using it to fuel an intense, high-velocity explosion reaching over 4,000 degrees Fahrenheit. In theory, such devices have the potential to suck in and incinerate chemical agents, however, no conclusive testing of such devices on live chemical agents has yet been conducted.

While they may have a better chance of destroying chemical munitions without releasing their agents, the blast and heat generated by thermobaric weapons are intensely deadly. Structures near the blast will be destroyed and persons not killed by the initial explosion or flying debris will suffer lethal damage to internal organs caused by the pressure wave it creates. The effect of their use in a populated urban area would cause casualties comparable to a small nuclear explosion or a chemical attack. Using a nonexplosive penetrator or a thermobaric device in a city such as Damascus could cause more civilian casualties than the regime’s attack on Ghutah, which is just the reason Assad’s forces are likely relocating their chemical assets closer to urban centers.

The ability to safely destroy large stocks of chemical agents with airstrikes is still unconfirmed, though it is theoretically possible. Testing that method now requires accepting that even relative success may mean killing thousands of the very Syrian civilians we would be acting to protect. As the American people and Congress consider the proposals for action made by the president and his cabinet they should be aware of the chances for success, the risks, and the potential cost in lives.

Why Chemical Weapons are a 'Red Line' the World Must Enforce

This article originally appeared in The Guardian on 4 September 2013.

Echoing President Barack Obama's remarks of a year ago, US Secretary of State John Kerry has called the use of chemical weapons a "red line for the world", asserting that evidence shows beyond a reasonable doubt the Assad regime used Sarin nerve gas against its own people. Failing to act now would push that red line back and send a message that the use of chemical weapons will be frowned upon, but that nothing will result other than stern international admonitions.

This would reverse the tide that has been rolling back the use of chemical warfare for the last 25 years. Chemical weapons are a world red line, and action is necessary to protect hard-won international progress against chemical weapons proliferation.

The long war against chemical weapons use

The first world war was the first occasion on which chemical weapons were used on a large scale in war. The results of these attacks, mostly on British and German soldiers, were so horrendous that a prohibition of their use was included in the 1925 Geneva Protocol – subsequently ratified by 138 nations. This was the first formal recognition that the use of chemical weapons is a red line for the world community.

The US and USSR took another step against chemical weapons by agreeing to cease production and set up an inspection regime in the1989 Wyoming Agreement. Then, in 1993, the world again pushed forward the red line to halt the production, stockpiling, and use of chemical weapons in the Chemical Weapons Convention (CWC).

The rest of the world has kept these agreements, and the reduction of chemical weapons has progressed steadily ever since. The Organization for the Prohibition of Chemical Weapons (OPCW), the enforcement agency of the CWC, has reported that 72% of the world's declared stockpiles have been eliminated, as of 2011. The rest are scheduled to decommissioned within the next few years. These are mostly located in Libya and Iraq, but crucially, they are secured and will be eliminated with co-operation from other CWC signatory states. The US has eliminated 90% of its chemical weapons and Russia over 60%.

There are reports of chemical weapons use by Russia, Vietnam, and Cambodia in the late 1970s and early 1980s. Saddam Hussein notoriously used chemical weapons against Kurds around Halabja, and during the Iran-Iraq war in 1988. However, there have now been no proven lethal chemical attacks in 25 years. Worldwide, the use of chemical weapons in war has virtually ceased since the 1993 adoption of the CWC.

Only Syria has continually chosen to ignore the world's red line on chemical weapons; it is one of only seven nations in the world that refuses to ratify the CWC. (It is joined only by Angola, North Korea, Egypt, and South Sudan; Israel and Burma/Myanmar have signed the CWC, but not ratified it.) At a time when the rest of the world was eliminating chemical weapons, Syria was actively stockpiling precursor chemicals and building what has become one of the largest chemical weapons arsenals in the world.

In July 2012, an official Assad regime spokesman, Jihad Makdissi, declared it was Syrian government policy that chemical weapons would not be used against Syrians, but reserved the right to use them against any external forces. So, Assad could not even keep his own declared red line on chemical weapons use. Unleashing nerve gas on noncombatants in Damascus was a big step over the line.

What about other conflict-zone 'red lines'?

Throughout the last century, the world has borne witness to violence throughout the world, including violent political crackdowns, ethnic cleansing, religious conflict, assassinations and border wars. In virtually every one, international law, norms and values – "red lines", if you will – have been stretched or broken. Victims and refugees caught in these conflicts have repeatedly called for intervention by outside powers. Most of these calls have been made on the United States and other western powers.

Sometimes, we have answered; most often, we have not. So what makes this "red line" different and why should we act this time?

The world order has been in turmoil since the fall of the Soviet Union in 1990 upended the geopolitical bipolarity of the previous 50 years. Former Soviet satellites in eastern Europe and the Caucasus continue to struggle for their own identity and to remain independent. The Arab Spring uprisings are tearing apart the old political order in the Middle East, while the rise of China is making its Asian neighbours nervous and attracting American attention. South American nations continue their journey out of poverty and away from repressive regimes.

Meanwhile, the US is coming to the end of over a decade at war, in Afghanistan and Iraq. Finally, we have already witnessed over 100,000 deaths in Syria.

Not all of the benefits the world was promised when the US and its allies prevailed in the cold war anti-Communist struggle have materialised. In some parts of the world, things seem to be regressing, rather than improving. That is why it is important to preserve and jealously guard what progress has been made in working toward a more peaceful world – even if that means turning to military action against rogue states in order to do so. The steady worldwide reduction of chemical weapons is a prime example of that progress – one that we cannot allow to be eroded so easily.

A failure to act after the Assad regime has crossed that red line would be akin to the world retreating and setting a new, weaker standard without a fight. No state other than Syria has dared to cross the line of chemical weapons use in a quarter-century. If we do not act today, we have set a new world precedent that says the use of chemical weapons is frowned upon, but there will be no serious consequences. We should not retreat so easily without serious consideration of what we would be sacrificing for the future.

Until this moment, the world was on the cusp of eliminating one of the unholy trinity of weapons of mass destruction. Quietly, steadily, we had been approaching the point where we would one day be able to say we had eliminated chemical weapons.

This is progress toward a safer world we can only hope to achieve with nuclear or biological weapons. Worldwide, proliferation of nuclear weapons has increased. Since the 1970 Nuclear Non-Proliferation Treaty (NPT), North Korea, India, Pakistan and Israel have developed new nuclear weapons. Other states, such as Iran, may be trying to join the nuclear club. Meanwhile, the nature of biological weapons makes tracking or controlling them difficult and there is no major international agreement specifically to enforce their prohibition. Though it receives less attention, the Chemical Weapons Convention is a real success story in comparison.

Syria is the last country in the world with a large stockpile of chemical weapons that refuses to eliminate them. Now, the Assad regime has used them on its own people. And Syria has threatened to use them against any outside forces which threaten the Assad regime. No other country in the world has dared do that since 1988.

President Assad is the last major roadblock to achieving a world free from the horror of chemical weapons. That is why the world, led by the United States, must take action in Syria.

Syria: Options for U.S. Invasion, Securing Chemical Weapons

This article originally appeared on PolicyMic on 24 August 2012.

The presence of chemical weapons in Syria has caused much debate since the statement by the Assad regime that they could be used against an outside invasion, but not against Syrians internally. There have also been questionable reports that the Syrian opposition is attempting to obtain or capture chemical weapons to use against regime supporters. "Anonymous diplomatic sources" have said the U.S. may need as many as 60,000 troops to "secure" Syria’s chemical stockpile. Others offer that the U.S. may send in special operations units. President Obama issued a warning to Assad that their use would shift U.S. policy toward intervening. There are many options on the table to deal with Syria’s chemical weapons.

Figures on both the left and right are supporting some form of intervention in Syria. Some hawkish commentators are pushing for an Iraq-style invasion, while others support an incursion similar to the successful Libya campaign and/or enforced "no-fly" zones as in Iraq. I have personally written in support of providing limited anti-armor weapons already present in the region and non-lethal support to the opposition to level the playing field against Assad’s well-equipped military.

The U.S. should not mount a full-scale invasion of Syria as long as the conflict remains local, doesn’t spread beyond Syria’s borders, and no other world or regional power provides large-scale military support to the regime. There is evidence Syria may be a growing proxy conflict on both sides, but not enough to justify the costs of an invasion in American lives and money. American national security is not directly threatened. However, ending the violence there is in our interest. That is another debate.

An invasion would upend the domestic character of the revolution the Obama administration has been careful to respect since the beginning of the Arab Spring two years ago. If the U.S. invades Syria, it would become responsible for the aftermath. A repeat of Iraq is certainly an undesirable outcome for America at this stage. Sending tens of thousands of troops into Syria to secure its chemical weapons is undesirable and unnecessary. The early stages of Afghanistan showed the folly of using "economy of force" or maneuver warfare and ignoring the Powell Doctrine, as did the lack of enough troops on the ground in Iraq to provide security which precipitated the need for a "surge." Sending troops into Syria with the goal of only securing chemical weapons would be a repeat of these conditions. Either send in enough troops to guarantee the success of the mission and security or do not send them in at all. There is no room for half-measures. These are lessons from Afghanistan and Iraq.

Syria’s chemical weapons and production facilities are spread across the country from Aleppo to Homs to Damascus. Putting troops on the ground to secure them would mean splitting our forces, which would necessitate communicable logistical and transport connections. The wars in Afghanistan and Iraq have shown that enemies who cannot match U.S. troops directly will attack their supply convoys on major roads. The conditions for U.S. troops on the ground in Syria would be similar to those on the ground in Iraq. Adding the difficulty and danger of guarding stockpiles of chemical weapons and transporting them for disposal, most likely wearing thick chemical protective equipment, makes a mass ground invasion the most undesirable option available.

There has been discussion of inserting special operations forces into Syria to secure these weapons. Such an operation would depend upon very accurate, complete information on where and under what conditions these weapons are being stored. The U.S. claims to have good knowledge of where these weapons are, but quickly and quietly removing what are probably hundreds or thousands of chemical munitions doesn’t have a great likelihood of success. They would probably have to be destroyed where they are using explosives that generate enough heat to incinerate the chemical agents, otherwise it risks a chemical agent contamination incident akin to a "dirty bomb" for which the U.S. would be responsible. The risk of a failed mission resulting in the capture or death of U.S. military personnel or the unintentional release of chemical agents causing civilian casualties makes this option undesirable as well.

A third option, the least of evils, would be to use air delivered thermobaric explosives to destroy the chemical munitions. The success of this option would also depend upon precise intelligence as to the location of the stocks and highly accurate placement of the explosive device to minimize the risk of an accidental release. It would also eliminate the need for operators on the ground to transport and place the explosive, though personnel on the ground could certainly provide highly accurate location information or guide an airstrike.

Currently the U.S. decommissions our own chemical weapons by incinerating the raw agents in temperatures above 2,000 degrees Fahrenheit. Thermobaric explosions exceed 4,000 degrees Fahrenheit in the radius of up to 500 feet around their epicenter, depending upon the size of the device used. Such temperatures would be enough to incinerate chemical agents and minimize the chances of incidental release of the agents or other lethal gasses from the resulting explosion.

This option is also far from perfect. It does have the advantage of reducing or eliminating the need for U.S. personnel on the ground inside Syria. It still depends upon very accurate and complete intelligence regarding the location of Syria’s chemical weapons. There is still great risk of collateral damage to nearby civilian populations, but using this option to eliminate these chemical weapons and preventing their use may save more lives. It must be considered if the use of these weapons is probable and imminent and if the risk of collateral damage from such an airstrike outweighs the outcome of destroying these chemical weapons.

This is indeed a hefty decision to make. We should all hope that the situation in Syria is resolved soon without the need for any intervention by the U.S. or other states. That truly would be the best outcome for everyone involved.

We Can Eliminate Chemical Weapons

This post originally appeared on The Truman Doctrine on 17 August, 2012.

The Syrian conflict has caused great international concern with daily reports of fighting. The humanitarian situation is worsening with Syrians in major cities left without medicine, food, or water. To add to the difficulty, an Assad spokesman recently discussed the possibility that Syria’s sizable chemical weapons stockpile could be used on any outside invasion force, though asserting they would not be used on Syrians. The questions lingering about Syria’s chemical weapons show why international weapons control regimes are important. The world needs to pay more attention to chemical weapons.

Among weapons of mass destruction, nuclear weapons have long been the most prominent in international concern. Along with the U.S., there are eight states armed with nuclear weapons, Israel likely an undeclared ninth. The Nuclear Nonproliferation Treaty (NPT), regulated by the IAEA, is the central international agreement governing nuclear weapons. Parties agree not to acquire nuclear weapons, to eventually pursue nuclear disarmament, and to use nuclear technology peacefully. The NPT became effective in 1970, some forty years ago, and it was predicted then that there would be as many as 30 nuclear states by now.

It has been estimated that as many as forty states have the knowledge to develop nuclear capability. Yet only four new states have joined the nuclear club. None are members of the NPT. The U.S. still possesses the most active nuclear weapons, but the bilateral New START with Russia promises to make progress toward the zero goal of the NPT. Despite problems with North Korea and ongoing multiparty talks with Iran on its nuclear program, the NPT and bilateral agreements on nuclear weapons reduction have gone a long way in slowing nuclear proliferation.

The outlook is not as positive with chemical weapons. It is thought that as many as seventeen states currently possess offensive chemical weapons capability. Despite chemical weapon use as early as WWI, the Convention on Chemical Weapons (CWC), regulated by the Organization for the Prohibition of Chemical Weapons (OPCW), was only implemented in 1997. Nuclear weapons have not been used offensively since 1945, but chemical weapons have been used offensively in the Middle East as recently as the 1980’s.

Chemical weapons are also much easier to develop than nuclear weapons. Nuclear weapons require more advanced technical knowledge and enrichment of nuclear material and the components required to build a bomb create a larger identifiable footprint. An advanced chemistry degree and common chemical plants are all that is necessary. Deadly nerve agents are made from phosphates that are readily available throughout the world and are widely used in agricultural production.

Concerns about chemical weapons aren’t limited to Syria. North Korea and Myanmar, non-CWC states, are suspected of possessing them. Evidence suggests non-member Israel may have them as well. Iran and China are accused of having clandestine programs, despite being parties to the CWC. There have also been successes. Albania, South Korea, and India have completely eliminated their stores. The U.S. has destroyed 90% of its stockpile. Russia, Serbia, and Libya are more than halfway complete. America, Britain, and other nations have contributed millions to overseas programs to assist other nations in eliminating their stockpiles.

The world needs to do more to eradicate chemical weapons. If similar focus is placed on them as on nuclear weapons, we can eliminate known stockpiles in member states by the end of the decade. This is something we can only dream of with nuclear weapons. International weapons control regimes work. The successes of the NPT and bilateral nuclear agreements show that the Chemical Weapons Convention can rid the world of these terrible and dangerous weapons of mass destruction.

Syrian Chemical Weapons: What They Are, How They May Be Used

This article originally appeared on PolicyMic on 25 July 2012.

On July 23, the Syrian Foreign Ministry informed the press that the regime of Bashar al-Assad would not use chemical weapons against the Syrian people. A spokesman stated, “Those weapons will only be used in the case of exterior aggression.” Syria has never officially acknowledged it has chemical weapons and spent the next day denying it - despite it being well-known among intelligence agencies and confirmed by the Syrian opposition. Chemical weapons in the Middle East are in the headlines again. So just what are these chemical weapons and how could they be used?

Syria is alleged to have Sarin and/or VX nerve agents. Roughly speaking, nerve agents kill by causing uncontrollable expansion and contraction of muscles in the limbs and organs of the body. When muscles contract, they do so because signals are relayed through nerve cells by a messenger substance, acetylcholine. To stop the contractions, the enzyme acetylcholinesterase dissolves the messenger substance. Nerve agents such as Sarin and VX block the enzyme and the messenger substance continues to be sent. This means that the muscles of the body continue to contract uncontrollably, eventually destroying organs and causing death. Depending upon exposure amount and time, it can cause death within minutes or days.

Sarin is a G-Series nerve agent. The G series was discovered by a German chemist developing pesticides in the 1930’s. The Nazis refrained from using nerve agents because they falsely believed the allies possessed them as well. Only after the war did America, Britain, and Russia learn of them. G-Series agents are ‘non-persistent,’ meaning that once they are deployed, they only remain effective for a short period of time and become inert generally within a day. They are often watery or gaseous in consistency and harmful upon inhalation or skin contact.

VX is a V-Series nerve agent. It was developed in the 1950’s by British scientists and later shared with America. ‘Persistent’ V-Series agents may remain effective for a few days or up to a month. In moderate temperatures with little rain or wind, they can last as long as five weeks. V-Series agents are thicker and oily in consistency and evaporate less quickly. Skin contact and vapor inhalation are both lethal.

Chemical weapons, fortunately rarely deployed, are an effective weapon for reasons other than their lethality. Persistent chemical weapons can be used to deny access to an area for a period of time. Gassing strategic passes, cities, or ports can deny an enemy access to them or cause them to avoid them. Non-persistent agents can be used to cover a retreat, interrupt rear-area supply bases or routes, or cause enemy casualties in preparation for an assault. Even trained militaries equipped with chemical agent protective clothing and equipment experience significant slowing of operations when forced to operate in a chemical environment. Chemical weapons can be deployed in a number of ways, including aircraft spray, artillery, missiles, and mines.

Chemical agents are among the most lethal weapons known to man. They are cheaper and easier to develop than nuclear weapons and more controllable than biological weapons. The possibility of Syria deploying nerve agents against a ground invasion is a serious threat that shows the desperation of the regime. It presses home the point that ground action there would be a much more serious proposition than many are inclined to believe.
