The phrase "stop feeding the troll" is exactly right. Iran has a vast number of problems. What it needs is someone to blame for everything that is wrong, and also for the repression that takes place. The only things that unify the populace is hatred of Israel and America. The former is nigh on impossible to change, but the latter can be.

They happily state that they are setting up new facilities for enriching Uranium and even where they are. Why? Are they angling for more hostility from the West? If they wanted a covert bomb, why not get Pakistan to enrich some and transport it across the border - no easy task by any means but that might be covert with the ability to say that there is a nuke on a medium range missile somewhere in Iran. As it stands they are bragging that in 5-10 years they might have the bits required, just in case Obama wants to look tough on foreign policy in an election year.

The best way to get change would be to stop sanctions, to as far as possible open Iran up. People don't revolt when they've nothing to loose, they do so when they see they've something to gain.

I don't really see what the problem of Iran having a nuke is. We've nutters in North Korea and Pakistan with them and that is apparently fine. If the aim was casualties, then biological and / or chemical weapons are quick, cheap and equally deadly - yet they've apparently not tried to use one (or else the West and Israel has an astounding track record of getting them all). The aim must be defensive - that any massive fleet might be vaporised.

So, get trading with them. Get them access to stuff. Show them that fear of the West is not justified - ideally by not having hostile troops on 3 our of 4 sides. It won't be flicking a switch, but I think that kicking the Islamic hornet's nests in the Middle East isn't working.
