John McCain, the same guy who sang Bomb, Bomb Iran, thinks that we need to bomb Syria. Why? Sure, I know that the Syrian government is killing their own citizens. The question is do we have a dog in this hunt? The answer is no. We don't have any national interest in Syria. There is no oil in Syria. There are no shipping lanes thru Syria. Our job is not to jump into every conflict in the world. As a superpower, our job should be to try to use all of the tools in our toolbox to try to stop the bloodshed. Bombing Syria should be one of the last tools that we pull out. (Personally, I don't think that bombing Syria will do anything beyond getting more civilians killed.)
From American Progress:
Syria’s complicated situation has defied efforts to formulate solutions that would end the bloodshed there while removing the Assad regime from power. In turn, this difficulty in determining how to achieve these objectives has made coordination between international actors even more problematic than usual. While there are hopeful signs emerging that international coordination is improving, the United States should make sure that this coordination produces consensus policy options for which key players can marshal international support regardless of their content. It is not enough for one player to develop a plan—it should consult and coordinate with its partners to push it forward. The United States can and should drive this process forward while remaining cognizant of the risks and costs of direct ground military intervention in Syria.
