WWIII is coming! Will North Korea or Iran end the world?

Well i happen to be iranian and i am concerned about our government. Not just the nuclear program but in general. Hopefully soon the people of iran with revolt against the government and overthrow them and create a democracy, which is what us iranians have wanted for a long long time. i dont know what to say about north korea. god knows what they are plotting over there, but they are too small to pose a threat.
