President Donald Trump and Secretary of State Marco Rubio said Iran must agree to a diplomatic deal or face potential U.S. military action.

The ultimatum signals a critical juncture in Middle East stability as the U.S. seeks to resolve disputes over Iran's nuclear program and regional influence without a prolonged war.

President Trump said on May 13, 2024 [1], that Tehran's options are limited. He said that Iran's options are either to make a deal or face a major military escalation [2]. Trump said that if Tehran does not agree to compromise arrangements with Washington, the United States will "finish the job" in Iran [1]. During these remarks, Trump mentioned the existence of three to four groups within the Iranian leadership [3].

Secretary of State Marco Rubio said these sentiments in a statement on May 25, 2024 [4]. Rubio said the U.S. will either have a good agreement with Iran or deal with it "another way" [4].

The diplomatic pressure follows a period of high tension. While some reports indicate the U.S. and Israel attacked Iran in February and maintained a shaky ceasefire since April, other accounts suggest no such prior attack was necessary [5, 6].

U.S. officials are pushing for a compromise to avoid further conflict. However, the window for diplomacy may be closing. According to reports, a ceasefire is unlikely to be extended beyond Wednesday evening Washington time without a formal peace deal [7].

Washington continues to maintain that a diplomatic resolution is the preferred path to ensure regional security, provided Iran agrees to the terms set by the current administration.

"Iran's options are either to make a deal or face a major military escalation."

The administration is employing a 'maximum pressure' strategy by combining the threat of military escalation with a final opportunity for diplomacy. By highlighting internal divisions within the Iranian leadership and setting a firm timeline for ceasefire expirations, the U.S. is attempting to force a rapid concession from Tehran to avoid a full-scale regional conflict.
