Iran funded shia uprisings all around the world in an attempt to shore up against sunni islamic hegemony funded by the Saudis.

They've killed assloads of americans and do NOT have our interest at hands.

And what other nations do you mean? North Korea? The people who used the stolen information from AQ Khan who helped Pakistan with information he stole from the dutch while working at a nuclear facility?

Iran IS an absolute shit country in dire need of reform and nuclear ambitions only entrench them into more legitimacy and not the liberalism that place is in dire need of.
