Anyone who's shocked in any way that Osama bin Laden may have been "hiding out in plain sight" deep within Pakistan should read one book to understand the deeply complicated and ultimately untenable relationship between the governments of the U.S. and Pakistan, especially their respective intelligence agencies.

It's called Ghost Wars by Steve Coll.

I highly recommend it as a backdrop for all that has happened in Afghanistan since 1979 and all that has happened surrounding U.S. involvement in Afghanistan/Pakistan since September 11, 2001.

The book may actually be more relevant than ever at this stage.  This next new phase in the U.S./Pakistan relationship may need to account for and rectify all the double dealing that's been going on for decades.
