Yes, Obama should arm the Syrian rebels, because they have a right to defend themselves. Obama has been wishy-washy on the issue, because he is not sure who he sympathizes with. If Obama is not going to commit troops, he should at least provide weapons that will give them the chance to defend themselves.
Syrians should not be allowed to bear arms even with consideration by President Obama. After the incident of the slaying of diplomats by the Syrian rebels, there should not be a treaty of arming such an irresponsible government. The mere mention of army Syrian rebels is just asking for trouble.
