This Peter Beinart piece is kind of interesting.
In 2009, Obama chose a Defense secretary and a national-security adviser Washington Republicans loved. This year, he’s chosen a Defense secretary and a national-security adviser they hate. The reason: he no longer needs to care as much what they think.
He’s definitely not thinking defensively. But I think the world has run out of people that the Republicans don’t hate. So, this was kind of inevitable.
