President Obama has asked Congress (and by extension the American people) for authority to order military strikes against Syria. In my view this request should be rejected.
I think American policy should embody a presumption against war. We should undertake military actions only when they are clearly in the national interest. The connection to the national interest in this case is extremely tenuous. Syria poses no direct threat to the US. There is a claim that Syria has violated an international norm. Be that as it may I believe a more important international norm is that nations shouldn't attack other nations absent an immediate and direct threat which isn't present here.
It is also very unclear what any American strikes are expected to accomplish. There appears to be a significant danger of mission creep. If our first strikes don't appear to accomplish much other than killing a bunch of people are we going to get more and more involved in an attempt to justify our earlier involvement?
In short I don't see a compelling case for military action so I would refrain.
