I agree. Trump loves to hobnob with the rich and powerful and meeting Fuentes was a stupid and arrogant decision.
Are Trump and his staff stupid? It is possible that the former President is alienated from the mainstream Jewish establishment. Despite Trump being the most pro-Israel President since Lyndon Johnson, it must be noted that Netanyahu immediately congratulated Biden upon the latter winning the Electoral College. Even Macron and Merkel were not so quick as Netanyahu. Remember that his son-in-law and daughter, who are Jewish, have declined to participate in his 2024 election campaign.
It is possible that the hostility of not only the Deep State, but Conservatism, Inc., has moved Trump to the alt-right. You must wonder if Trump is well advised.
