Fusionism brought these views together into what seemed for a long time, at least from the outside, to be a relatively workable political coalition. Philip Zelikow, a veteran Republican foreign-policy official and one of hundreds of prominent members of the Party who vigorously opposed Trump in 2016, said, “World War II, followed by nearly World War III, brought the United States into an unprecedented world role. And a vocal minority didn’t accept it. They don’t like foreigners. They think they’re playing us for suckers. There were a lot of Pearl Harbor and Yalta conspiracy theories that we’ve forgotten about. This group concentrates overwhelmingly in the Republican Party.” For a long time, it was kept in check. Now, in Zelikow’s view, it has grown in prominence and become less deferential to the business wing of the Republican establishment, and is “close to being the most influential element in the Party.”
