Last week I attended a foreign policy conference in Washington that featured a number of prominent academics and former government officials who have been highly critical of the way the Bush and Obama Administrations have interacted with the rest of the world. Professor John Mearsheimer of the University of Chicago was on a panel and was asked what, in his opinion, has been the most notable foreign policy success and the most significant failure in the past twenty-five years. The success was hard to identify and there was some suggestion that it might be the balancing of relationships in strategically vital Northeast Asia, which "we have not yet screwed up." If I had been on the panel I would have suggested the Iran nuclear agreement as a plus.

As for the leading foreign policy failure there was an easy answer, "Iraq" which was on everyone in the room's lips, but Mearsheimer urged one not to be so hasty. In reality the Iraq disaster has killed hundreds of thousands, has cost trillions of dollars and has unleashed serious problems for the Mideast region in general while allowing the rise of ISIS, but in "realistic foreign policy terms" it has not been a catastrophic event for the United States, which had hardly been seriously injured by it apart from financially and in terms of reputation.
