“I don't think [Ahmadinejad is] a “mad man.” He's an individual who is very committed to his view and ideology. There's almost a sort of apocalyptic mentality that reigns here and he's not alone in it. Unfortunately, there are a few people who may sign up for that kind of a point of view. The problem is that we have this kind of regime represented by such individuals who have taken, first-and-foremost, the Iranian people hostage for the past 30 years and who are completely uninterested about the state of our own citizens. They are only interested to use Iran as a base from which to launch what was from the very beginning the exploitation of a theocracy and Islamic ideology across the planet as a challenge to the rest of the world… I think you should take him very seriously. The last time the world was not quite sure about the final threat was at the time of Hitler in Nazi Germany and we know the rest of the story. If we look at these kind of regimes that have been completely merciless vis-à-vis their own population; who have been brutally shooting our youth on the streets simply because they ask for their freedom; and are willing to stop at nothing to intimidate the whole world to submit to their demand, I think we should take it very seriously.”
