First off, Ahmadinejad's involvement in the embassy takeover is what we call a "controversy" not a "fact". Second, he's an antisemite, he hates Israel, everybody knows it, stop talking about it. That bit about Israel is actually part of a larger phrase he said which in summation means "Israel will cease to exist". For clarification, he made the speech once, not numerous times, and it didn't include anything about he himself wanting to destroy Israel. That third paragraph of yours is actually that same speech, so you should be able to see how there is no intention in there.
He is a hateful crazy bastard, but he's not to be taken seriously. As for conflictmongering, that's exactly what we're doing. Some of America's politicians now are trying to initiate another "preemptive strike", and fix us up with another trillion-dollar catastrophe that people can remember us by. If that's not conflictmongering, I don't know what is.
