Putting 2 and 2 and 2 together on Iran

I don't remember where, but there was a recent report that the Iranians and Americans had come to something of an understanding, the Iranians would rein in their actions in Iraq in exchange for the US lowering the temperature on the nuclear charges.

If that was the case, it appears to have broken down.

(AP) "The U.S. has recently shared new intelligence with the International Atomic Energy Agency on key aspects of Iran's nuclear program that Washington says shows Tehran was directly engaged in trying to make a bomb, diplomats said Thursday."

(Reuters) "Iran is testing an advanced centrifuge at its Nations nuclear complex, diplomats said on Wednesday...." (Today's WaPo version is more inflammatory.)

(Reuters) "Iran has postponed a fourth round of talks with the United States in Baghdad on improving security in Iraq, giving no reason for the delay, Iraqi Foreign Minister Hoshiyar Zebari said on Thursday."

Worth watching.
