(CNN) The most dismaying of Pew's findings is that the drop in regard for America goes well beyond Trump. Sixty-four percent of the people surveyed expressed a favorable view of the United States at the end of the Obama presidency. That has fallen to 49 percent now. Even when U.S. foreign policy was unpopular, people around the world still believed in America -- the place, the idea. This is less true today.
In 2008, I wrote a book about the emerging "Post-American World," which, I noted at the start, was not about the decline of America but rather the rise of the rest. Amid the parochialism, ineptitude and sheer disarray of the Trump presidency, the post-American world is coming to fruition much faster than I ever expected.
