I just was wondering how the purpose of setting this up benefits America's interest.
Oh, I agree. How does it help us? No clue.
This is really tinfoil hat stuff, but John Brennan was accused earlier in the year by a disgraced former FBI agent (that investigated the William Jefferson ordeal and was also the FBIs lead guy on the Muslim Brotherhood) of being a converted Muslim.
When that news leaked, there were other rumors that this was long held to be true.
Heck, even in Zero Dark Thirty, wherein the directors and producers were given unprecedented access to files, there is a character purported by some to be Brennan called "The Wolf" that is on a prayer mat when introduced as a character in the CIA headquarters.
That doesn't answer your question because who knows if there is a logical answer.
There are some tinfoil hat type anecdotal explanations...like Brennan aided the MB that could be plausible, but are highly unlikely, I would assume.
