Donald Trump said a 20-year [1] halt to Iran's nuclear development is sufficient to end combat between the two nations.

The statement outlines a potential framework for long-term stability in the Middle East by demanding a verifiable cessation of nuclear activity. This approach suggests a shift toward a time-bound agreement rather than an indefinite ban.

Trump said during a press briefing on board the presidential aircraft on Friday, May 15, 2026, while returning from China [2]. He focused on the necessity of a verifiable, long-term halt to Iran's nuclear program as a primary condition for negotiations [2].

Regarding the duration of the freeze, Trump said, "20 years is enough. But the level of guarantee is the problem. It must be a real 20 years" [3]. He said that all highly enriched uranium currently held by Iran must be removed [3]. Trump said he would intervene if those materials were not recovered at an appropriate time [3].

During the briefing, Trump also addressed the role of China and the security of the Strait of Hormuz. He denied making any specific requests of the Chinese government regarding the strategic waterway. "We have no need to ask for favors," Trump said [3].

The former president's comments emphasize a strategy of maximum pressure combined with a specific timeline for disarmament. By setting a two-decade benchmark [1], he aims to create a window of stability that prevents Iran from regaining nuclear capabilities in the near future.

"20 years is enough. But the level of guarantee is the problem."

This proposal signals a preference for a concrete, time-limited agreement over the open-ended diplomatic frameworks seen in previous nuclear deals. By tying the cessation of combat to the removal of highly enriched uranium and a 20-year freeze, the strategy seeks to neutralize Iran's immediate nuclear threat while maintaining a credible threat of intervention to ensure compliance.
