The State Department or the Defense Department?

Stephen Walt has a very interesting article about true successes on the international stage by us.  He mentions the following: the Marshall Plan, Bretton Woods, the GATT & the WTO, the Non-Proliferation Regime, the Opening to China, the Egyptian-Israeli Peace Treaty, German Reunification, NATO, the Dayton Accords, the first Gulf War.  Of course, there are others, but the previous are the ones that came most readily to his mind.  His point being that these successes were the result of diplomacy, where the use of force played little or no role.  It's very difficult to list any real military successes since WWII.  Yet we, as a nation, are relying more and more on war rather than diplomacy.  Is he missing something?
