Trump threatens Iran with "higher level" strikes if it won't accept a peace deal, but says it's too soon for direct talks after reporting diplomatic progress.

The Trump administration said last week that the war had run its course, but the U.S. president and Israel’s prime minister in interviews on Sunday did not rule out renewed combat.

U.S. President Donald Trump is sending his envoys Steve Witkoff and Jared Kushner to Pakistan on Saturday for talks with Iran. The pair are expected to meet Iranian Foreign Minister Abbas Araghchi.

Trump appears keen to reach a deal to end the war, which is unpopular with Americans, as he deploys both pressure and diplomacy, analysts say.

Trump’s graphic compared the length of the Iran war to the Afghanistan War at 543 weeks, the Iraq War at 457 weeks, the Vietnam War at 439 weeks, the U.S. Civil War at 209 weeks, World War II at 196 weeks, the Korean War at 161 weeks, and the War of 1812 at 139 weeks.
