I, and I assume many other Americans, want to see PROOF of this sarin attack. Not just some video tapes, some politician in DC telling us he's seen the proof, etc. The politicians need to have and show this country they have positive proof that Assad actually carried out these attacks. Anything less is insufficient justification for this attack. STAY OUT of Syria. They have nothing we need or want. Let the backward tribes kill each other off with whatever means they have at their disposal.
