Iran may have problems in it's own country – but it is not threatening the US. Also very much with the problem of Israel's invasion into Palestine, which has seemingly unlimited amounts of nuclear weapons, helped in particular by the US, and does not need to disclose even how many it has, Iran does need nuclear weapons, and has every right to them. The argument that at some time in the future it may have a rogue leader is not enough. Any country that has nuclear weapons could at some stage a rogue leader, including the US.
