“Biden on that stage calling the president of the United States a clown and a liar is not something Biden would have done four years ago under any circumstances,” he said. “That he felt he has to do it is a sign to outsiders that American culture is in a cycle of decline.”
Thomas Gomart, director of the French Institute of International Relations, said that the debate strengthened the impression “that the United States has retreated from the global stage and withdrawn into itself.” Trump, he said, “has explicitly walked away from the position of a global leader, and Joe Biden may be implicitly doing so, too.”
Hard to disagree.
