To whomever brought up the sniper rifles: That connection, at least, appears to be bunk.

I like the video, but the presence of Iranian-made weaponry does not say anything about how it got into Iraq. It could have been bought on the black market, for instance. (And if it were, that would, conversely, not be evidence that Iran wasn’t involved: countries routinely use the black market to disguise what are essentially arms transfers).
I will be vastly unsurprised if it turns out Iran is arming Shiite groups in Iraq. But proving Iranian involvement is going to be very tough indeed, unless they’re caught in the act of delivering it.
And that doesn’t even address the question of who is arming the Sunni insurgents.
Nor does it get at *how much* of the weaponry is Iranian. As the major noted, Iraq is awash in unfathomably huge amounts of leftover ordnance.
