U.S. President Donald Trump on Wednesday said that the ceasefire between Iran and Israel is “going very good,” following a week of intense military exchanges between the two nations.

Speaking at the NATO summit in The Hague, Trump credited his diplomatic intervention for helping de-escalate tensions. “Israel came back yesterday,” he told reporters, referencing his earlier warning to Tel Aviv to halt further airstrikes on Iran.

Trump also issued a strong warning to Tehran regarding uranium enrichment, stating the U.S. would not tolerate any effort to revive its nuclear program. “We will not let that happen. Number one, militarily. We won’t,” he said.

He described the recent U.S. strikes on Iranian nuclear sites as “total obliteration” and reiterated that if Iran rebuilds its nuclear facilities, Washington would strike again. “Sure,” he said when asked directly if further strikes were on the table.

The recent conflict saw Israel launch major airstrikes on Iran on June 13, targeting nuclear and military facilities and killing top commanders, nuclear scientists, and civilians. Iran retaliated with multiple drone and missile attacks on Israel.

The escalation peaked over the weekend when the U.S. bombed Iran’s Fordow, Natanz, and Isfahan nuclear sites. Iran responded by targeting the U.S. Al Udeid Air Base in Qatar with missile strikes.

Trump subsequently announced a ceasefire would begin at 0400 GMT on Tuesday. Both Iran and Israel later confirmed adherence to the truce.

Despite the ceasefire, Trump warned Iran against restarting uranium enrichment, stressing that the U.S. remains prepared to use military force if necessary. He also hinted at a possible future relationship with Iran but made it clear that any nuclear ambition would be met with force.
