I think the issue was that none or very few of these people who were actually willing to fight. This was one of Obama/McCains' biggest problems. The people they were willing to arm were not willing to fight. So whatever arms we sent got divided up among the bad guys, and this is how Obama/McCain ended up arming the Syrian versions of Al Queda/ISIS. It was no coincidence of timing that when the flow of those arms ceased was also when Assad began to retake territory. There were other factors to be sure, but this was one of them.
