If the United States had armed the good rebels, assuming that we could have even identified them, then it is inevitable that those arms would have ended up in the hands of ISIS or one of its jihadist allies either via trades between the groups or by theft. Moreover, it is apparent that there was little that we could have done to stop our supposed allies from continuing to finance the more radical elements of the rebellion, just as they did in Libya. ISIS, which people tend to forget used to go by the name al-Qaeda in Iraq during the U.S. occupation, would have gained much the same influence over the Syrian rebellion that it had before, then, the only difference is that they would have done so with U.S. supplied weapons How exactly we would have been better off in this world that Clinton and the others wanted to create is beyond me.
