Has Iran committed an act of war against the US by supplying the Iraqi terrorists with weapons to attack American troops -- including specially designed bombs with the ability to pierce American armor?

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."

Screw their nuclear program -- if this is actually the case, then the Iranians are engaged in intentional acts against American military personnel. Time to take action.
