A plan laid out in documents stored on Osama Bin Laden’s compound outlined a mission to send the United States into a crisis by assassinating then-President Barack Obama and leaving the “totally unprepared” Joe Biden in charge.

First reported by the Washington Post in March of 2012, the terror leader’s plan was to take out a plane carrying the U.S. commander-in-chief, in addition to his top military commander, David Petraeus.

“Obama is the head of infidelity and killing him automatically will make Biden take over the presidency … Biden is totally unprepared for that post, which will lead the U.S. into a crisis,” wrote bin Laden to one of his advisers.

He also referred to Gen. Petraeus as “the man of the hour,” saying that killing him would “alter the war’s path” in Afghanistan.

The documents highlight the al-Qaeda leader’s continued focus on attacking Americans. To one of his deputies, he wrote that it was important to remain concentrated on “every effort that could be spent on attacks in America.” Bin Laden instructed regional leaders to “ask brothers in all regions if they have a brother … who can operate in the U.S.”

At the time, U.S. analysts and administration officials clarified that there was no evidence to suggest that any of the plots detailed had materialized, despite the disturbing content of bin Laden’s documents.

Biden’s own narrative on his position surrounding the strike that killed bin Laden has been shaky over the years. At times saying he told then-President Obama not to order the strike, but changing his mind every so often to claim he supported the movement.
