WASHINGTON (MCT) — Osama bin Laden was devising a strategy for overthrowing Afghan President Hamid Karzai and controlling Afghanistan once the U.S. left the country, said a former U.S. official familiar with the cache of notes and letters that were seized last year in the raid on the terrorist leader’s compound.

Bin Laden had discussed his plans with the Taliban leadership council, known as the Quetta Shura, and the Haqqani network, which controls the North Waziristan tribal area in Pakistan, said the former official, who spoke on the condition of anonymity while discussing the intelligence.
