President Trump faces the significant challenge of tackling three critical global crises: nuclear weapons, climate change, and artificial intelligence. Addressing these issues effectively could be the ultimate test of his ability to negotiate and make lasting deals.

In October 2025, during a dinner for donors, President Trump unveiled a model of a proposed triumphal arch. His aspiration to leave a legacy as a great leader is clear. However, his efforts may face challenges due to the temporary nature of physical symbols. Buildings can be renamed, and structures can be dismantled, erasing the visible marks of his presidency.

The reputation of a presidency is shaped by more than just physical monuments. To secure a lasting place in history, achievements in addressing crucial issues like nuclear weapons, climate change, and AI are vital.
