Does the possibility (likelihood?) that Syrian government forces have used sarin gas strengthen the case for military intervention or at least great U.S. involvement?
Pro-intervention hawks like Sen. John McCain certainly think so and have been quick to remind everyone that President Obama called chemical weapons use a "red line." But McCain has been a vocal advocate of greater U.S. action for quite some time, which suggests that the use of chemical weapons hasn’t really altered his thinking at all. Nonetheless, it is also worth noting that far more sensible commentators — such as former CIA analyst Emile Nakhleh — also view these reports as an additional reason to topple Assad sooner rather than later.
But why? Nobody should be pleased that Assad’s forces (may) have used chemical weapons, but it is not obvious to me why the choice of weapon being used is a decisive piece of information that tips the balance in favor of the pro-intervention hawks. It’s been obvious for decades that the entire Assad regime was nasty, and it’s been equally clear that the government forces were using lots of destructive military force to suppress the opposition. How else did 70-80,000 Syrians die over the past two years? It’s not as though Assad has been acting with great restraint and sensitivity to civilian casualties and then suddenly decided to unleash sarin gas. Does it really matter whether Assad is killing his opponents using 500-pound bombs, mortar shells, cluster munitions, machine guns, icepicks, or chemical weapons? Dead is dead no matter how it is done.
The case against direct U.S. intervention never depended on believing that Assad was anything but a thug; rather, it rested first and foremost on the fear that intervention might make things worse rather than better. Specifically, it has rested on the interrelated concerns that 1) the fall of the Assad regime might unleash an anarchy of competing factions and warlords, 2) the opposition to Assad contained a number of extremist groups whose long-term agendas were worrisome, and 3) pouring more weapons into a society in the midst of a brutal civil war would create another Afghanistan, Iraq, or 1970s-era Lebanon. These prudential concerns still apply, irrespective of the weaponry Assad’s forces have chosen to employ. And if his forces have used chemical weapons, then one might even argue that it raises the risks of intervention and thus strengthens the case against it.
This is not an open-and-shut issue, and there are obvious points to make on the other side. Obama did suggest that chemical weapons use might be a "red line," in what was a fairly transparent attempt to deter Assad from going down that road. So one might argue that Washington would incur some loss of credibility if it does not respond now. Although I think we routinely exaggerate concerns about our credibility, that doesn’t mean that it is of no concern at all. Nonetheless, Obama’s prior statements do not require any particular response, and the administration certainly shouldn’t do something unwise simply because it feels it has to do something.
One might also argue that chemical weapons are a form of WMD and that allowing Assad to get away with their use will undercut the existing taboo against these weapons. There’s a case for that point of view, but I think it exaggerates the supposedly "unique" lethality of chemical weapons. Sarin is very bad stuff, but it is not like a nuclear weapon. Nor should we forget that governments can sometimes kill lots of people using rather simple weapons — in the Rwandan genocide, they did it with machetes — and the overwhelming number of deaths in Syria have occurred through conventional means.
Like Senator McCain, I find my position on this issue unchanged by the revelations about possible chemical weapons use. I still see Syria as a tragically vexing policy question. It is heart-wrenching to see what is happening there and the instinct to "do something" is understandable, but the downsides to direct or indirect military involvement remain formidable. I certainly think we should be doing more to help refugees and to minimize the destabilizing effects of the carnage on Syria’s neighbors. I am all in favor of continued diplomatic pressure on Russia and China to end their support for Assad, and the chemical weapons report may provide additional leverage on that point. (See here for some useful thoughts along those lines). But I hope that Obama doesn’t allow himself to be bullied into doing a lot more simply because of these reports, unless he is convinced that doing more now reduce the risks later on.
