Nonproliferation? How Quaint!

In years to come — assuming, for the purposes of argument, there are any years to come — scholars will look back at President Obama’s Nuclear Security Summit and marvel. For once, the cheap comparisons with 1930s appeasement barely suffice: To be sure, in 1933, the great powers were meeting in Geneva and holding utopian arms-control talks even as Hitler was taking office in Berlin. But it’s difficult to imagine Neville Chamberlain in 1938 hosting a conference on the dangers of rearmament, and inviting America, France, Brazil, Liberia, and Thailand . . . but not even mentioning Germany.

Yet that’s what Obama just did: He held a nuclear gabfest in 2010, the biggest meeting of world leaders on American soil since the founding of the U.N. 65 years ago — and Iran wasn’t on the agenda.
