President Obama has gotten much attention from a single extended response he gave to a question about his foreign policy from Ed Henry of Fox News in a press conference last week in Manila. The apparently strongly felt need, on the part of some of the president's hardline critics, to strike back at his remarks and to try to discredit them indicates that he spoke some embarrassing truths. Garden-variety disagreement with the substance of the president's policies and what he has said to support them would never have stimulated this kind of response.

The president made several perceptive observations about the less productive aspects of current discourse in Washington about Ukraine, Syria, and other difficult issues, but if there was a single “ouch” line that made the critics most uncomfortable it may have been Mr. Obama's comment that “for some reason many who were proponents of what I consider to be a disastrous decision to go into Iraq haven't really learned the lesson of the last decade, and they keep on just playing the same note over and over again.” It must be painful for Mr. Obama's opponents to be reminded how right he was about this issue while so many others—Democrats as well as Republicans—were wrong.

Some of the rest of us who have commented repeatedly on the lessons of that war could be accused (although the president, who is not a serial gloater on the subject, cannot) of playing our own note over and over again. It ought to be played—because the Iraq War was the biggest and costliest U.S. endeavor ever in the Middle East, because we continue to suffer from the domestic as well as the regional consequences of that misadventure, because what was bad about that war has parallels in what could easily happen with some current issues if they are not properly handled, and because it is astounding that the biggest promoters of the Iraq War somehow still seem to have an audience even though they have been proven to be guilty of gross malpractice as policy analysts.

If there is any ground for criticizing what the president said at the press conference in Manila, it is that he seemed implicitly to accept some of the simplistic frames of reference that characterize not only what his critics are saying but more general discussion in the United States of foreign policy. There is the tendency in that discussion, for example, to register anything good or bad happening in the world as a success or failure of the incumbent U.S. president. Thus Mr. Obama pointed to how security relations between the United States and the Philippines are far better today than they were a decade ago, without mentioning that some of the reasons for that really don't have much to do with his own foreign policy. There also is the tendency, amid the slapping on of sanctions against adversaries hither and yon, to treat someone else's pain or isolation as if it were an end in itself. Thus Mr. Obama stated that “Russia has never been more isolated,” without quickly pointing out that any isolation of Russia is only a means to try to induce certain changes in Russian behavior. But the president was, after all, only giving an impromptu response to criticism, and he did not make any specific claims about the meaning and significance of Filipino cooperation or Russian isolation.

If subsequent commentary by the critics were to be believed, the main takeaway from the president's remarks was that he was accusing his political opponents of being warmongers. But the president explicitly acknowledged, in referring to debates over Syria and Ukraine, that the opponents he has in mind have disavowed wanting to send U.S. troops into such conflicts. Mr. Obama's main point was instead that after making such disavowals, the critics either (1) fail to spell out what other action they have in mind, beyond what the administration already is doing; or (2) to the extent they do mention an alternative, fail to assess carefully the likely consequences both good and bad, and instead just make unsupported assertions that acting more boldly or aggressively will somehow help to solve the problem at hand.

The president's point is valid. In fact, it applies as well to a lot of criticism of the foreign policies of other U.S. presidents. It is a reflection of the luxury of non-incumbency. Only incumbent policy-makers have to come up with a course of action that, despite all the downsides, is most likely to help solve problems. Non-incumbent critics can sit back and carp about problems that are still unsolved, whether or not solution is really within the capability of the United States.

Charles Krauthammer is one of those critics whose nerve evidently has been struck by the president's comments. His reaction gives evidence of having been thrown into a spasm upon first hearing the comments and never going back to reread the transcript. He begins, for example, with the assertion that Mr. Obama “began with a complaint about negative coverage on Fox News.” Actually, in response to Henry's statement that “there have been a lot of unflattering portraits of your foreign policy right now,” the president simply observed that “there are actually some complimentary pieces as well about my foreign policy, but I'm not sure you ran them,” which falls short of a “complaint” about Fox's coverage, however much such a complaint would be warranted.

Krauthammer goes on at length on the theme of people being falsely accused of warmongering. He issues a challenge to name any U.S. political leader “who has called for sending troops into Ukraine,” disregarding that the president was not accusing anybody of doing that and instead specifically said his critics were not calling for that.

Trying to turn tables, Krauthammer writes, “wasn't it you, Mr. President, who decided to attack Libya...? Yes, it was, and there is significant valid criticism yet to be written about that decision. But it would not be Krauthammer who would be positioned to write it; he applauded the military intervention in the Libyan civil war and only wished at the time that the intervention had come sooner. He does not mention that fact, nor does he say anything about what lessons the continuing mess in Libya may hold for possible intervention in other Middle Eastern civil wars.

Another topic on which the Obama administration can be validly criticized was the drawing of a “red line” about chemical weapons use in Syria. But what needs to be criticized was the drawing of the line in the first place, not that the administration “retreated abjectly,” as Krauthammer puts it, because the administration never did that. Instead, the administration with help from the Russians made lemonade out of the lemon of a red line and won an agreement that already has resulted in the destruction of Syria's capability to manufacture prohibited chemical weapons and removed from Syria for destruction nearly all of the regime's stockpile of the weapons. This is a far greater blow in favor of the cause of nonproliferation and non-use of chemical weapons than anyone hoped for before the Syria war even began. And as Robert Golan-Vilella reminds us, it is hard to see how any cruise missile strikes on Syria merely to show that we are willing to use military force would have done an iota of good in the Syrian situation.

On Ukraine, Krauthammer does identify one specific policy alternative to what the administration has done so far—providing lethal aid to the Ukrainian military—and argues that this would get Putin to shape up. “The possibility of a bloody and prolonged Ukrainian resistance to infiltration or invasion would surely alter Putin's calculus...” he says. Surely it would, but there would likely be bloody and prolonged Ukrainian resistance with or without U.S. lethal aid. One question is whether such aid would change the prospective length and bloodiness of the resistance enough to make a critical difference in Putin's calculations. Another question is how much weight such an effect would have relative to any provocative effects of the United States, the leader of NATO, initiating such a military relationship with Ukraine. Krauthammer does not bother to address either question.

Just below Krauthammer's column on the same Washington Post opinion page is a piece by House Armed Services Committee chairman Buck McKeon, which is another “what, me a warmonger?” reaction to the president's comments in Manila. Besides the forced indignation over presidential accusations that were never made, this item is characterized mainly by unsupported assertions, without even an attempt to get at the multiple underlying questions that would have to be analyzed, that military saber-rattling always means less chance of war breaking out and more chance of reducing the intensity of wars already underway. On Syria, for example, McKeon says that “arming moderate rebel factions and restoring the U.S. military posture in the Mediterranean” could have prevented use of chemical weapons “or even shortened the conflict.” How? The divisions among opposition groups, the domination of the more extreme ones, and the fight-to-the-death determination of the regime's supporters make very unlikely that a further (beyond what Gulf Arabs were doing anyway) arming of the hard-to-identify “moderates” would have had such desired effects. And just what sort of threat would be implied by any further U.S. military deployments in the Mediterranean? You do seem to believe, Mr. Chairman, that we need to be willing to carry out threats that we make.
