No not at all.
I don't think he's really much like a traditional dictator in his character. People compare him to PUtin, I think that's a real misunderstanding of what kind of person he is and his interests.
Whatever we could say about Putin's moral character, his motivations is very much political control, he has specific policy and goals he wants, and he is very hard working.
I don't think Trump has much interest in politics really, and he's not especially a hard worker, or driven. I don't think he particularly enjoys the work of being president.
The biggest issue with losing the election for him was about his ego. And if he reached the end of his term limit, that wouldn't have any implications for his ego.
