And another thing: caution the US on Iran.
For a sober assessment, read Simon Jenkins in The Guardian:
If ever there were a country that was once ripe for soft-power diplomacy, it was modern Iran. Yet the west misread Ahmadinejad and then misread such dissenters as Mohammad Khatami and parliament’s speaker, Mehdi Karroubi. It defied pleas from moderates not to impose sanctions, rejecting the argument that Iran needed a strengthened professional, commercial and academic class as counterweight to the military and the mullahs. As with the sanctions imposed on Saddam’s Iraq, Gaddafi’s Libya and Mugabe’s Zimbabwe, they have driven Iran’s rulers into a siege economy. Sanctions weaken the forces of pluralism and opposition. They are plainly counterproductive.
