Michael Totten notes:
I don’t know what’s going on in Iran, but a second nuclear facility has reportedly just exploded. This one, in Isfahan, is where uranium was being enriched.
Tehran denies it. Israeli officials say the explosion was deliberate, but decline to say whether or not they are responsible.
UPDATE: I have to say that if Iran’s nuclear weapons problem is effectively destroyed this way–without leading to even a localized war let alone a regional war because Tehran so desperately wants to deny that anything is even happening–those who have argued for years that we should learn to live with an Iranian bomb will look ridiculous.
Me, I'm wondering; is Israel's threat to attack just a cover to distract from agents inside Iran chipping away at the program? Hope so. Obama is no help at all in this situation. A harder stance against Iran's nuclear ambitions would have made today's situation less volatile, not more. Iran isn't afraid of sternly worded letters from Obama. I bet they get tired of all the booms though.
