President Donald Trump said Monday that Iran faced "decapitation" if it did not agree to a pact aimed at ending the conflict between the two nations. His remarks signaled a sharp escalation in tone as he pressed Tehran to accept an agreement.

Trump's comments presented the proposed deal as an urgent choice for Iran rather than a long negotiating process. Based on the remarks, he appeared to suggest that Tehran had very little time left to reach an understanding with Washington.

The statement adds to already tense U.S.-Iran relations, with the White House using unusually severe language to describe the consequences of failing to secure a pact. The focus of Trump's message was clear: an agreement to end the confrontation is being framed as the only acceptable outcome.

Attention will now turn to whether Iran responds publicly and whether any diplomatic track emerges from the latest warning. For now, Trump's language has put renewed emphasis on the pressure campaign surrounding a possible U.S.-Iran deal.
