Trump’s comments Sunday came hours after Tehran said, according to state media, that it sent a response to the peace plan through Pakistani mediators. The back and forth follows an exchange of hostilities around the Strait of Hormuz in recent days that highlighted the fragility of a ceasefire the two sides reached more than a month ago.

In a news conference Monday carried by Iranian state media, Foreign Ministry spokesman Esmaeil Baqaei defended the Iranian proposal as “reasonable and generous” and called on the United States to meet Iran’s demands: “ending the war, lifting blockades, halting maritime piracy, freeing frozen assets and ensuring security in the Strait of Hormuz and security in Lebanon and the region.”

Iranian news outlets indicated that the proposal was similar to Tehran’s position during the previous negotiating exchange: calling for an official end to the war, the reopening of the Strait of Hormuz, withdrawal of all naval vessels enforcing a U.S. blockade, lifting of U.S. sanctions, an effective ceasefire in Lebanon, and an additional 30 days of talks to iron out the details. Iran has proposed that all discussion of its nuclear program be the subject of subsequent negotiations.

Trump, in a separate Truth Social post on Sunday, accused Iran of “playing games with the United States” and of “laughing at our now GREAT AGAIN Country. They will be laughing no longer!”
