Who used the weapons? Was it Assad or the “Rebels”? Who gave them to the user? Iran?. Our foreign “Fast and Furious”? Many questions. Few answers and once again to “Pass the bill to find out whats in it”. No thanks.
That is the key question. Even if it can be shown that the Syrian army used the gas (which I doubt), then the next question becomes: Was it ordered by Assad, or was it done by a rogue officer?
No matter. Obama will say something along the lines of: "We have proof that Assad ordered the attack. You must take my word for that. The proof is classified, so you cannot see it."
That won't be good enough for the majority of Americans. But who cares about them? It will be good enough for the majority of Congress.
