Prospects for a US-Iran agreement to end the conflict remained uncertain on Friday, May 30, 2026, with President Donald Trump stating he would make a "final determination" on a deal. Simultaneously, Iranian officials emphasized that no understanding had yet been finalized.

Iranian chief negotiator Mohammad Bagher Ghalibaf indicated that Tehran would evaluate any agreement based on actions, not just words, asserting that no steps would be taken by Iran unless Washington acted first. This diplomatic uncertainty unfolds against a backdrop of continued regional hostilities.

Iranian Foreign Ministry spokesperson Esmaeil Baghaei confirmed that exchanges with the United States are ongoing but reiterated that no final agreement has been reached. He rejected Trump's demands-based approach and characterized the US naval blockade as illegal. Baghaei added that Tehran would gauge any easing of restrictions by concrete actions rather than mere pronouncements.

Meanwhile, Israeli Prime Minister Benjamin Netanyahu reported that Israeli forces had advanced beyond Lebanon’s Litani River. Israeli attacks across Lebanon on Friday reportedly resulted in dozens of civilian casualties, including killed and wounded.

US Central Command (CENTCOM) announced that its forces are "present and vigilant" across the region, sharing an image of an F-16 fighter jet on patrol. In Singapore, at the Shangri-La Dialogue, US Defense Secretary Pete Hegseth outlined Trump's plan for a $1.5 trillion defense investment, describing it as a significant expansion of America's military-industrial base. Hegseth also urged allied nations to increase their defense spending to at least 3.5 percent of their gross domestic product, warning of potential shifts in bilateral relationships for those that do not comply. He reaffirmed the US commitment to preventing Iran from acquiring nuclear weapons.

The US Department of Defense described military-to-military talks between Israeli and Lebanese delegations held in Washington as "productive," noting that discussions focused on regional security and stability. The Pentagon also reiterated its support for Lebanon's sovereignty and territorial integrity.

Reporting from the White House, Al Jazeera's Alan Fisher indicated that a meeting in the Situation Room involving President Trump had not provided clarity on whether a final agreement with Iran had been reached. Fisher suggested that any potential easing of restrictions by the US would be judged by Iran based on tangible actions.

The situation remains fluid, with the US administration signaling a "final determination" is pending while Iran maintains that negotiations are ongoing but have not yet yielded a conclusive agreement. The ongoing military activities in the region, particularly the Israeli advance into Lebanon, add a layer of complexity to the diplomatic efforts.
