Marc Lynch makes it:
[T]he U.S. should not be contemplating military intervention in Syria. Risky, costly foreign policy decisions can not simply be taken to express moral outrage. They need to have a serious chance of success. None of the military options currently under discussion have a reasonable chance of improving the situation at an acceptable cost, and their failure would likely pave the way to something far worse.
