There are the big three of weapons of mass destruction: biological, chemical, and nuclear.Big RR wrote:Andrew--while I disagree with what you propose re unilateral action, I appreciate your genuine concern re use of chemical weapons against civilians. But I will ask you, is this concern limited only to chemical weapons, or are there other weapons whose use against civilians must/should be met with the same response (even unilaterally)? I am trying to assess the scope of responsibility you are saying the US must assume to make war somehow more civil.
And I venture to guess that if the Assad regime had thrown nuclear weapons around, this board would be nearly unanimous in demanding that someone -- the UN, NATO, the Arab League, the US, someone -- make sure that the Assad regime did not do so again.
I have emphasized the use of chemical weapons against civilians, because that is what occurred in this instance. In the context of your question, however, we should recall that using chemical weapons against anyone -- civilians or combatants -- violates a peremptory norm of international law. As does using biological or nuclear weapons against anyone.
There are hard questions here. If one side uses biological, chemical, or nuclear weapons, does that circumstance justify the other side's doing likewise. (Under international law, the answer is "no," but that might not be the first time that international law has failed to accord with international reality. Which is not necessarily a bad thing: Much of international law must be candidly regarded as aspirational, and there is a valuable place for aspiration in international relations.)
But that is yet another reason for someone -- the UN, NATO, the Arab League, the US, someone -- to act in the face of the Assad regime's use of chemical weapons: If no one does anything, the opposition (or some faction(s) of the opposition) may feel entitled to do likewise, which leads to a chemical-weapons holocaust.
