U.S. Secretary of State Marco Rubio affirmed on Saturday that the United States will not allow Iran to acquire nuclear weapons, emphasizing his country's commitment to preventing Tehran from developing such weapons.

Rubio made these remarks during a meeting of NATO foreign ministers held in Brussels, Belgium, where he stated, "President Donald Trump is closely monitoring this issue and is eager to know the next steps regarding it."

He added, "No country in the world wants to see Iran possess nuclear weapons," noting that "Washington will continue its diplomatic and security efforts to ensure that Tehran is not enabled to achieve this goal."

It is worth mentioning that U.S. President Donald Trump previously revealed that he had sent a letter to Iran's Supreme Leader regarding reaching an agreement on the nuclear program.

Trump explained that Washington is considering two paths to resolve the crisis—military and diplomatic—but prioritizes negotiations, signaling ongoing diplomatic efforts to address nuclear disputes.

In 2015, Iran, along with Britain, Germany, China, Russia, the United States, and France, reached a nuclear agreement that included easing sanctions on Tehran in exchange for imposing restrictions on its nuclear program.

In May 2018, the United States withdrew from the agreement during Trump's first term and reimposed sanctions on Iran, prompting Tehran to gradually reduce its nuclear commitments and abandon restrictions on research and uranium enrichment levels.
