I can say with certainty that the Quds force, a part of the Iranian government, has provided these sophisticated IEDs that have harmed our troops. And I'd like to repeat, I do not know whether or not the Quds Force was ordered from the top echelons of government. But my point is what's worse – them ordering it and it happening, or them not ordering it and it happening? And so we will continue to protect our troops. ... to say it claim is provoking Iran is just a wrong way to characterize the Commander-in-Chief's decision to do what is necessary to protect our soldiers in harm's way. And I will continue to do so. ... Whether Ahmadinejad ordered the Quds force to do this, I don't think we know. But we do know that they're there, and I intend to do something about it. And I've asked our commanders to do something about it. And we're going to protect our troops. ... I don't think we know who picked up the phone and said to the Quds Force, go do this, but we know it's a vital part of the Iranian government. ...What matters is, is that we're responding. The idea that somehow we're manufacturing the idea that the Iranians are providing IEDs is preposterous. ... My job is to protect our troops. And when we find devices that are in that country that are hurting our troops, we're going to do something about it, pure and simple. ... does this mean you're trying to have a pretext for war? No. It means I'm trying to protect our troops.
