There have been atrocities on both sides of the war and Tulsi has never denied that. Her point is the sooner the war ends, the sooner the atrocities will end. First of all, Assad has already won the war. He’s not going anywhere. Second, the alternative to Assad is al-Qaeda/ISIS, which will be far worse for the people of Syria. Without the west’s support, the “rebel” terrorists would have been stopped a long time ago and the people of Syria could begin to rebuild their war-torn country.
