Won't be fooled again

So, the US produce proof that Iran are supplying weapons used against Allied troops in Iraq. It's a shame they couldn't be so accomodating in providing proof of American weapons used to kill British troops in Iraq.

But what kind of proof is this:

a) "Proper, bona fide, hard physical evidence" proof, or

b) "Do you reckon we can sucker the American people in believing more bull-s**t so we can invade another country without a good reason" proof ?
