ABC News:

NATO officials say they have caught Iran red-handed, shipping heavy arms, C4 explosives and advanced roadside bombs to the Taliban for use against NATO forces, in what the officials say is a dramatic escalation of Iran’s proxy war against the United States and Great Britain. …

The coalition analysis says munitions recovered in two Iranian convoys, on April 11 and May 3, had “clear indications that they originated in Iran. Some were identical to Iranian supplied goods previously discovered in Iraq.”

The April convoy was tracked from Iran into Helmand province and led a fierce firefight that destroyed one vehicle, according to the official analysis. A second vehicle was reportedly found to contain small arms ammunition, mortar rounds and more than 650 pounds of C4 demolition charges.

A second convoy of two vehicles was spotted on May 3 and led to the capture of five occupants and the seizure of RPG-7mm rockets and more than 1,000 pounds of C4, the analysis says.

Also among the munitions are components for the lethal EFPs, or explosive formed projectiles, the roadside bombs that U.S. officials say Iran has provided to Iraqi insurgents with deadly results.

Supplying arms to our adversaries to be used against American and British forces is obviously an act of war. But if the Bush administration did what it ought to do and took military action against the odious fundamentalist Islamic Iranian regime, what would be the domestic American reaction?

The left would say very much what Mr. M says here:

My official reaction: Aw crap.

You’ll have to forgive my cynicism here, first, because to me this has an awful lot of Iraq flavor to it with a hint of “Meeting with al Qaeda in Prague,” and just a touch of yellowcake. Which just goes to show that hte whole story of the boy who cried wolf might just have a bit of truth to it.

In the worst case scenario where this is true… uh-oh. …

We caught them red handed, we must bomb them. John McCain can provide the soundtrack.

But let’s remember something folks. Good things take time. Really really crappy things are rushed, and I implore everyone to read this story with a dose of judicious caution because we have heard this story before. On the surface it doesn’t make sense, Iran is Shi’a, Taliban Sunni, and we have seen how well they play together.

This is reminiscent of the old OBL Saddam Hussein meme. Ooh, their in bed together except, they weren’t, and no sane thinking mind would think that considering that Saddam was a secularist, and bin Laden ran al Qaeda are hardcore extreme fundamentalists.

We must not jump the gun and consider this another reason to leap to war. First the report must be verified and vetted. Second, we must stop a second and look at what is going on. Is this a sign to make war, or is this yet another sign on the road saying we have already gone way too far.

The left has its talking points already prepared: the administration is lying, Iran is innocent and no threat; or, on the other hand, if Iran is a threat, that’s really terrifying, and we better retreat.
