Not to derail the thread, but I think it'd be more interesting as a creative exercise to imagine a world where Trump had run for president, and won, during the first cycle he floated the possibility of doing so - the 1988 election.
Imagine Trump handling the American response to the collapse of the Warsaw Pact, desire for German reunification, the Tianamen protests, the fall of the Soviet Union, and Saddam Hussein's aggression in the Middle East. Quite a pivotal and delicate time in world history, and we were lucky to have competent US leadership during that period.
