First of all, the anti-war left, like ANSWR and Not In Our Name, are not really pacifists at all. They are only opposed to US involvement in war because of the power differential. The anti-war left has supported every two bit dictator around the world that has been willing to take on the US. The anti-war left are really anti-capitalists.
If you have been paying attention, you will have noticed that the Black Bloc were spotted in Egypt, fighting along side the Muslim Brotherhood and also in Gaza. Of course, it could have been ISIS, since their costumes are the same. Maybe their agenda is overlapping.
