Barrel bombs. 1) Barrel bombs are cruel explosives that are not precise but that is quite characteristic of the Syrian regime and its brutality. 2) Car bombs and indiscriminate shelling by armed Syrian groups are not less cruel. 3) You need to remember that Western bombs in Iraq and Afghanistan are probably or even certainly far more cruel and savage (and far more devastating) than barrel bombs. 4) Barrel bombs were used by the Lebanese Army against the Nahr Al-Barid refugee camp but Western government not only did not condemn their use, they even supplied the explosives, ammunition and helicopters. Spare me fake moral outrage.
