Yes indeed. Why has there been no investigation of what would be a serious intelligence breach? I think I know the answer. There was no breach. Iran informed the IAEA on the 21st and the U.S. and its cronies reacted by trying to put Iran's disclosure in the worst possible light. Obama personally briefed Medvedev hoping to elicit an anti-Iran statement and thus trap him in a policy. But it didn't work. Medvedev made a vague statement about sanctions and probably was later briefed by his own people who told him that Iran was simply digging a hole in the ground. The lack of investigation of this alleged Iranian intelligence coup is the clearest sign of American hysterics.
