This Is Rumor Control, a new web site composed of various intelligence analysts and journalists, is reporting that Iran has decided to confront US forces in Iraq. I hope this is not true, but based on the recent murmurings on Iran on the talk shows and rumors from military people, I'm not dismissing it.

The Guardian reports:

The US charge sheet against Iran is lengthening almost by the day, presaging destabilising confrontations this autumn and maybe a pre-election October surprise. The Bush administration is piling on the pressure over Iran's alleged nuclear weapons programme. It maintains Tehran's decision to resume building uranium centrifuges wrecked a long-running EU-led dialogue and is proof of bad faith. The US will ask a meeting of the International Atomic Energy Agency on September 13 to declare Iran in breach of the nuclear non-proliferation treaty, a prelude to seeking punitive UN sanctions.
