Responses to "anti-war" arguments

Full disclosure / Note: At the point where I am writing this, I support a U.S. attack on the Syrian regime. This and this (by Frederic Hof and @michaeldweiss respectively) are probably the closest articulations of my position so far. To give you some context, more generally, politically, I'd say I tend to be more or less to the left of the spectrum (real left not U.S. left).

I decided to write responses and thoughts on common, bad, or good arguments I read or hear against U.S. intervention in Syria. Maybe I'll change my mind, convince others, or learn something in the process.

Here are the arguments and responses I have collected so far:

• "Anti-war" argument #1: Evil people want the U.S. to intervene
• "Anti-war" argument #2: America's enemies are killing each other, let them be
• "Anti-war" argument #3: Violence breeds violence
• "Anti-war" argument #4: Public opinion is against a strike

Hope this proves useful/interesting!
