Iran should die. Seriously.

[N-Man]

The population - or the youth, at least - is probably the only one in the Middle East that could be trusted not to elect extremists, were they operating in a democratic system. The current state is well entrenched though, so I don't know how feasible a peaceful revolution like in the ex-USSR states would be. The pro-Russians and Shi'ites (in Lebanon) never had the support of the military and paramilitary like the Ayatollah does.

I would recommend simply waiting for the old generation to die off, but the nuclear issue makes things relatively more complicated.
