Trump says the Iran war ends the day after the midterms, and so do oil prices

President Donald Trump gave the Iran war a new end date on 9 September: the day after the 3 November midterm elections. He spoke on the tarmac at Joint Base Andrews before flying to Dallas for the Republican Party's first midterm convention.

"I think the war is going to end immediately after the election because they can't hold out any longer," he told reporters. "They're desperate to try and affect the election so that we can get a nice weak group of people in there and leave them alone and let them have their nuclear weapon."

He said oil prices would fall on the same timetable. "Right after the election, oil prices are going to be tumbling downward." Gasoline, he added, could later go below $2 a gallon, though that would take longer than the midterms. A negotiation with Tehran is still possible, he said, but "not something we're looking at."

A war in its seventh month

The conflict that began earlier this year is now in its seventh month. On Tuesday the US Central Command said it had destroyed five Iranian oil tankers after attempted strikes on a Navy ship. Four were hit in the Gulf of Oman and one near Kharg Island. Iran's Islamic Revolutionary Guard Corps answered by firing at the Muwaffaq Salti Air Base at Azraq in Jordan, a facility used by US forces, and by claiming attacks on ten ships near the Strait of Hormuz.

Jordan said it intercepted 18 of 20 missiles and reported no casualties. Two missiles fell in unpopulated areas. Brent crude settled at $101.21 on Tuesday, the first close above $100 since July. West Texas Intermediate settled at $96.05. AAA put the US average for regular gasoline at $4.22 a gallon, up from $4.01 a month earlier. Diesel is near $6.

Those prices are the political problem. Midterms on 3 November will decide whether Republicans keep slim majorities in both chambers. Trump's approval ratings have fallen to a record low in several recent polls, driven by the war and the cost of living. Republican candidates have been telling the White House that another two months of $100 oil is a campaign fact, not a talking point.

What the prediction does and does not commit

Trump has called the war a detour and an excursion. Earlier forecasts of a short campaign did not hold. The new line does two things at once. It blames Tehran for the calendar, and it tells voters that relief on fuel is 55 days away if they accept the premise that Iran is bargaining against the election rather than against US and Israeli military pressure.

Nothing in the remarks described a ceasefire text, a residual force, or who would police Hormuz after a stop. The Treasury on Tuesday added 36 Iran-related sanctions aimed at aviation, including another attempt to ground Mahan Air. Those steps point to a longer squeeze, not an overnight close.

The Dallas convention is itself a novelty. Republicans have not staged a midterm convention of this size before. Trump used the trip to argue that the war and prices will break the other way once the votes are counted. Markets will test that claim every session until 3 November. So will the next exchange of fire in the Gulf.

For European and Asian importers already paying the $100 barrel, the practical question is narrower. If the president is right, the premium built into winter inventories should start to unwind in early November. If he is wrong, the United States will enter the next Congress with the same war, the same tanker risk and the same pump price that he just tied to the election.
