Professor Stephen Walt holds a chair in international relations at Harvard. He has a blog on FP in which he comments on current events, etc. etc. In his latest posting " What the appointment of Hagel means and doesn't mean " he reflects on the Obama appointment - that is, subject to Senate approval - of John Kerry and Chuck Hagel as Secretaries of State and Defence respectively. "First, as I noted a week or so ago, I don't think Hagel's appointment implies any shift in policy direction. It's been clear for quite some time what the general thrust of Obama's national security policy is going to be: trimming defense, pivoting to Asia, rejecting preventive war with Iran, and striving to rebuild at home. To the extent that he used the sword overseas, it was through limited, surgical means like special forces and drones and not big U.S. deployments. (The Afghan surge is the exception, of course, but I think Obama learned his lesson on that one)....
Old enough to know better, young enough not to care.
