Up until the mid 90s at least Saddam Hussain DID have chemical weapons, its possible they were destroyed before 2003 and it was mistaken intelligence the US had, its possible they were transported to Syria so the US intelligence was right then again its possible Bush was lying doesn't matter. Syria though DOES have possibly the largest chemical weapons stockpiles in the world. The whole world confirms its existence, the UN confirms its existence and even Assad has confirmed its existence so I think its pretty safe to say Assad has these weapons. In the case of their use recently is been verified by the US, a variety of other countries and the UN so this is no conspiracy either. Obama wants to do everything to avoid a war with Syria because he knows if anything goes wrong he can very quickly find himself with another Iraq on his hands which will end up being a very long and very expensive operation. Obama wants to put on a show of stremgh to satisfy international pressure then say ok I done my bit and call off the whole operation. He does not wish to bring down Assad or help the rebels just the minimum required to satisfy international public pressure and then he can go back to business as usual condemning Assad every time the new casualty list is announced.
