Note that while Amedinejad & Co. have said many outrageous things, they have not done much at all to harm Isreal or anyone else. Iran has never invaded another country, nor started any wars (since ancient times). Even if Iran aquired nuclear weapons I would not worry that they would use them irresponsibly. To think so is basically ignorant. The reason the US fears Iran is that we would lose much of our influence in the region if Iran became a nuclear state.

Also, Amedinejad is essentially saying the same things Khomieni said about Isreal, making this nothing new for Iran's leadership. Frankly, I think there will never be peace in the Middle East until Isreal is dissolved or substantially chnaged.
