Donald Trump has made two primary promises regarding a new agreement with Iran. His central goal is to ensure that Iran can never obtain nuclear weapons. He aims to create a deal that is significantly more comprehensive and effective than the one negotiated by Barack Obama. The focus is on establishing stricter long-term constraints on Iran's nuclear capabilities. Trump believes a more rigorous approach is necessary to guarantee global security. However, the feasibility of fulfilling these promises remains a point of political debate. The outcome will determine if Trump can successfully redefine U.S. policy toward Iran.
