Gates

According to Gates the decision to move militarily was given to far-left adviser Samantha Power.

[S]imilarly, in a battle over defense spending, “I was extremely angry with President Obama,” Gates writes. “I felt he had breached faith with me . . . on the budget numbers.” As with “don’t ask, don’t tell,” “I felt that agreements with the Obama White House were good for only as long as they were politically convenient.”

Gates acknowledges forthrightly in “Duty” that he did not reveal his dismay. “I never confronted Obama directly over what I (as well as [Hillary] Clinton, [then-CIA Director Leon] Panetta, and others) saw as the president’s determination that the White House tightly control every aspect of national security policy and even operations. His White House was by far the most centralized and controlling in national security of any I had seen since Richard Nixon and Henry Kissinger ruled the roost.”

It got so bad during internal debates over whether to intervene in Libya in 2011 that Gates says he felt compelled to deliver a “rant” because the White House staff was “talking about military options with the president without Defense being involved.”

Gates says his instructions to the Pentagon were: “Don’t give the White House staff and [national security staff] too much information on the military options. They don’t understand it, and ‘experts’ like Samantha Power will decide when we should move militarily.” Power, then on the national security staff and now U.S. ambassador to the United Nations, has been a strong advocate for humanitarian intervention.

Another time, after Donilon and Biden tried to pass orders to Gates, he told the two, “The last time I checked, neither of you are in the chain of command,” and said he expected to get orders directly from Obama.
