i would team up with stalin to beat hitler... not sure how much rope i'll give putin to bomb raqqa
As far as bad guys go, Nazis and ISIS really seem neck and neck regarding the degree of brutality they're willing to impart on their subjects.
If ISIS had 1940s German capital behind their efforts this wouldn't be a question, but they still have that 'JV' look to some folks. Because their capabilities are indeed relatively limited makes them less of a threat, but not really any less evil.
I'm willing to turn a blind eye to it if it stays there, and a blind eye toward Putin helping Assad put a coffin lid on it too.
