President Donald Trump said Tuesday that he faces a major decision over the future of the conflict with Iran, telling world leaders at the United Nations that Tehran could either reach an agreement with the United States or face the destruction of the Islamic Republic.

“Will a deal be made with Iran?” Trump asked during his address to the U.N. “Or, do I annihilate the Islamic Republic, and do it quickly?” He also questioned whether the United States should leave Iran the opportunity to rebuild or prevent the regime from continuing to threaten other countries.

Trump's comments came as both the United States and Iran sent signals that diplomacy could potentially resume. Iranian President Masoud Pezeshkian is also attending the U.N. General Assembly, while Iranian officials have indicated that their delegation has authority to negotiate.

Trump had previously described himself as approaching a major crossroads on Iran. In an interview last week, Trump said he was considering whether to resume large-scale military attacks or pursue another path toward ending the conflict. He also said he wanted to hear directly from Gulf leaders about the next steps.

The conflict has continued to affect the broader Middle East, including tensions surrounding the Strait of Hormuz and attacks by Iran-backed Houthi forces. Iranian officials have warned that renewed U.S. military action could lead Tehran to expand the scope of its response.

Trump has repeatedly maintained that Iran will not be allowed to obtain a nuclear weapon. With the U.N. gathering bringing American, Iranian and regional leaders to New York, the president's remarks put renewed attention on whether the conflict will move toward negotiations or another escalation.
