Trying to make critical sense of the current state of foreign affairs is treacherous business for anyone, but for an historian it comes close to pursuing a death wish. Even with all the advantages of hindsight, the past remains shrouded to varying degrees, while decoding the present is like trying to see through a blinding sandstorm of events. But if there is much that remains unclear, at least the basic frame of mind of Donald Trump’s presidency is known. Recently, Stephen K. Bannon, the President’s Svengali, looked forward to the “deconstruction of the administrative state” in America. Given the tenor of Trump’s comments on international issues over the past year—about foreign trade, NATO, China, nuclear weapons, Russia, the Middle East, etc., etc.—the dismantling of the American-led world order that has been in place since the end of World War II is also a real possibility.
