"[His response to a question about his concerns regarding the “militarization” of foreign policy] We all ought to be concerned. Defense and military leaders are not shy about highlighting the debilitating tendency— across administrations of both parties—to invert the roles of force and diplomacy. We’ve all quoted Secretary of Defense Bob Gates’ line about the military having more musicians than we have Foreign Service officers, and Jim Mattis’ point about needing to “buy more ammunition” if we continue to underinvest in diplomacy. But that hasn’t made much of a dent, I’m afraid. Of course, we ought to ensure that our military is stronger than anyone else’s, that our tool of last resort is potent and durable. And of course, force or the threat of force has an important role to play in the conduct of diplomacy. We’ve all benefited from having the U.S. military focus the minds of those who sat across the table from us... But time and time again, we’ve seen how overreliance on military tools can lead us into policy quicksand. Time and time again, we’ve fallen into the trap of overusing—or prematurely using—force. That comes at much greater cost in American blood and treasure, and tends to make diplomacy a distorted and under-resourced afterthought. In the forever wars of the post-9/11 era, the “great inversion” [of force and diplomacy] also tended to thrust State Department professionals into nation-building roles that are beyond the capacity of American diplomats, or any other external power. While our colleagues served with courage and ingenuity, the fact remains that we’re the American Foreign Service, not the British Colonial Service."
