There is no such thing as a trustworthy rebel group, non of the rebels answer to anybody but themselves and whats Obama going to do if the trustworthy rebels do with the weapons that are not approved of, place sanctions on them? What happens if one of these trustworthy rebels with their advanced American gets killed by Hezbollah or an Al Quaida affiliated rebel group? How will Obama explain himself to the American public when Al Quaida shoot down an American civilian plane or an Israeli fighter jet sparking a full scale war with Israel? Whats Obama going to say if American antio tank rickets find their way into Afghanistan and are used against American armoured vehicles killing American soldiers? What happens if Hezbollah get hold of some and give them to Iran to be reverse engineered? Once Assad is topple. Once Assad falls the rebels will not return any unused weapons back to the US with a thank you note they will instead be sold on the black market. Obama is either being naive or he is burying his head in the sand intentionally so he can say he is doing something about the war without actually using the military. This is a civil war and civl wars should be left to the citizens of that country to fight out between themselves without outside intervention trying to help one side or another to win. Lets all just leave the Syrians to fight it out and then when it ends we formerly recognise the new government whoever it is even if its Assad because if he does send weapons he risks making turning this conflict regional.
