The more I think about it, the more I marvel at Ahmedinejad's political genius.
However predetermined US plans may be to attack Iran, at every opportunity, Ahmedinejad takes the lead.
"You are familiar with history. Aside from the Middle Ages, in what other point in history has scientific and technical progress been a crime?" the letter asks.With one letter, Ahmedinejad set US military plans back at least a few months.
There is no way that the US can follow up this letter with a bomb without destroying whatever's left of its image around the world - and setting us up for economic disaster.
Now, for the US to attack Iran (with the least political fallout), there has to be a hostile intervening incident to neutralize the conciliatory gesture embodied by this letter.
