Is Osama bin Laden dead?

We've heard the reports before: Osama bin Laden is dead. Often, they've come from very questionable sources.

But the latest OBL dead report comes via a respected errorism expert, Michael Ledeen, author of The War Against the Terror Masters and a resident scholar at the American Enterprise Institute. Here's what he's says in an NRO article:

According to Iranians I trust, Osama bin Laden finally departed this world in mid-December. The al Qaeda leader died of kidney failure and was buried in Iran, where he had spent most of his time since the destruction of al Qaeda in Afghanistan. The Iranians who reported this note that this year's message in conjunction with the Muslim Haj came from his number two, Ayman al-Zawahiri, for the first time.

I hope you read Ledeen's whole article. I plan to comment on it tomorrow.
