Is Bin Laden in Iran?

Michael Ledeen thinks so:

Meanwhile, the director of central intelligence gently reminded us — or so it appears — that we have profound problems to resolve with the mullahs. Time asked him how we were doing in the hunt for Osama bin Laden. He replied that the matter was rather more complicated than one might imagine, even though, he said in so many words, he was quite sure he knew where the master terrorist was located. I think he told us that bin Laden is in Iran. Judge for yourself:

...we have some weak links...until we strengthen all the links, we're probably not going to be able to bring Mr. bin Laden to justice. We are making very good progress on it. But when you go to the very difficult question of dealing with sanctuaries in sovereign states, you're dealing with a problem of our sense of international obligation, fair play...

Is he not saying that bin Laden is in a sanctuary in a sovereign state? And what state could that be? If bin Laden were in Afghanistan or Pakistan, it wouldn’t seem to be such a vexing problem as Goss suggests. But Iran, now that’s a problem. Indeed the biggest problem in the war against terrorism.
