There are two distinct conversations going on about the legitimacy of the West’s expected military campaign against Syrian president Bashar al-Assad. The first has to do with whether military action is an appropriate response to the wanton violation of a near-universally held norm -- in this case, the taboo against the use of chemical weapons, which the Assad regime allegedly violated last week. The second centers on whether military action is an appropriate means for protecting civilian populations from atrocities (of whatever kind) committed by their governments. These conversations, although often conflated, have very little to do with one another, since each policy goal as the goal of protecting civilians. It has more to do with protecting a set of shared international understandings about the proper conduct of warfare. If the goal were really to protect civilians, the West would have intervened long ago: bombs and guns have killed far more civilians, at least as horribly, as last week’s gas attack.
The Obama administration has already confirmed that its primary concern is with protecting the norm and punishing its violators. Given that goal, the appropriate course of action would be to, first, independently verify who violated it. The United States claims that it has “no doubt” that Syria was behind last week’s chemical attack, but that remains an open question until the UN inspectors have completed their investigation. Second, the United States would have to consider a range of policy options for affirming, condemning, and lawfully punishing the perpetrator before resorting to force, particularly unlawful force. As Article36.org, a nongovernmental organization notes, these might include condemnation, an arms embargo, sanctions, or any of the other bilateral and multilateral measures that are typically used to respond to violations of weapons norms (and which might be at least as effective as air strikes, if not more so). Third, should the United States decide on military action, with or without a UN Security Council resolution, it would need to adhere
