If you read only one thing about Iran today, make it Gary Sick's analysis of the Obama administration's approach.
And, speaking of the Obama administration, Sick's analysis dovetails with Andrew Sullivan's broader analysis. Which has some similarities to my analyses that I can't immediately find links for.
Speaking of getting it wrong, here's a good analysis of what far too many people get wrong about Central Asia. My limited time there showed me very little Islam. My hosts said that they were Muslim, but they seemed to be in the same way that people who go to church only on Easter are Christian. But there were gigantic monuments in the Russian style, many of them commemorating those who died in the Great Patriotic War, World War II to us.
And, yeah, if you still want to read more about Iran, check out Nuclear Diner.
