Michael Gerson complains  about the “abandonment” of “American exceptionalism”:
During the Barack Obama years, the United States retreated from internationalism in practice. At first, this may have been a reaction against George W. Bush’s foreign policy. But Obama’s tendency became a habit, and the habit hardened into a conviction. He put consistent emphasis on the risks of action and the limits of American power.
One of the more tedious arguments from hawks over the last eight years is that the U.S. “retreated” under Obama. This was always false, and there was no real “retreat” from the world. Nonetheless, the lie became a habit and it has since hardened into conventional D.C. wisdom. Obama didn’t “retreat” from internationalism, but the purpose in promoting this falsehood was to identify internationalism with extremely meddlesome interventionism and to treat everything else as the rejection of internationalism. This nonsense made for a somewhat useful talking point so long as hawks didn’t get too specific about what they meant, but when forced to describe what Obama’s “retreat” was they had to acknowledge that they meant that he didn’t start or escalate enough wars to their satisfaction. According to them, Obama’s big failing is that he didn’t involve the U.S. enough in the killing of Syrians. To put it mildly, that is an odd understanding of what internationalism means.
The abuse of the concept of “American exceptionalism” has been similar. Once again, hawks insisted that Obama didn’t believe in it, misrepresented his words to shore up their garbage argument, and then repeated the lie for years until it became automatic. In the process, they ended up defining “American exceptionalism” so narrowly that no one except advocates for a very aggressive foreign policy could qualify as supporters. Gerson’s complaint that Obama emphasized risks and costs of direct military action in Syria reflects this. If a president doesn’t use American power to inflict death and destruction somewhere overseas, or if he even pays closer attention to what it will cost the U.S. to do so, Gerson thinks that amounts to an “abandonment” of what makes America unique. That’s profoundly warped, but unfortunately it is what passes for “idealism” in foreign policy commentary these days.
