A question

If Thomas Rick's account is accurate with the following assertion:

As Centcom commander, Fallon was technically Petraeus's new boss. In practice, however, Petraeus bypassed the chain of command and answered directly to Bush, enjoying what was probably the most direct relationship between a frontline general and his commander in chief since the Civil War.

then Petraeus was also bypassing Gates and whoever else is in between Gates and Fallon in the chain of command. Fallon is gone, and Petraeus is now the head of Centcom.

While Petraeus was acting directly under the orders of Bush, Gates was out of the loop didn't say anything.

So, [drum roll] the question is: who is now giving Petraeus his orders? Anyone?
