New IED's Coming Into Iraq From Iran

ABC News is reporting a story that I'm sure will go on the Administration's list of "why regime change in Iran would be a good idea" (h/t The Corner):

U.S. military and intelligence officials tell ABC News that they have caught shipments of deadly new bombs at the Iran-Iraq border.

They are a very nasty piece of business, capable of penetrating U.S. troops' strongest armor.

What the United States says links them to Iran are tell-tale manufacturing signatures -- certain types of machine-shop welds and material indicating they are built by the same bomb factory.

"The signature is the same because they are exactly the same in production," says explosives expert Kevin Barry. "So it's the same make and model."

U.S. officials say roadside bomb attacks against American forces in Iraq have become much more deadly as more and more of the Iran-designed and Iran-produced bombs have been smuggled in from the country since last October.

"I think the evidence is strong that the Iranian government is making these IEDs, and the Iranian government is sending them across the border and they are killing U.S. troops once they get there," says Richard Clarke, former White House counterterrorism chief and an ABC News consultant. "I think it's very hard to escape the conclusion that, in all probability, the Iranian government is knowingly killing U.S. troops."

If we're looking for a good reason to take action against the Iranian government, this is almost an engraved invitation.
