Top advisers to US President Donald Trump are pushing to keep the Iran war from escalating before November's midterm elections in an effort to staunch Republican electoral losses, according to four people familiar with the discussions. The strategy is already under strain as the United States and Iran resume back-and-forth attacks.

White House officials will consider ramping up military action after the November 3 vote, the sources said, who requested anonymity to describe internal thinking, though any return to full-scale conflict is far from a given.

For now, the administration is focused on tightening economic pressure on Iran in an effort to extract concessions in any future negotiation that months of military action failed to secure.

"We are keeping the pressure on Iran," one White House official said. "But November is a priority."

Keeping the war mostly contained until then would help prevent the unpopular conflict from dominating the news as Trump's Republicans campaign to defend thin majorities in the Senate and House of Representatives, the sources said.

Only 31% of Americans approve of the war, while some 63% disapprove, according to a late August Reuters/Ipsos poll, and voters are particularly unhappy about high gas prices.

A tactical pause could also give the US military some breathing room to replenish its heavily depleted munitions stockpiles, the sources said.

But pulling off the play-it-cool strategy looks more difficult by the day. While the conflict remains much less intense than it was during the spring or during a flare-up in the middle of the summer, both sides have exchanged tit-for-tat strikes in recent days.

Recent exchanges

Over the weekend, the US struck rocket launchers on Iran's Larak Island after a month of relative calm, prompting Iran to fire missiles toward Jordan and the United Arab Emirates. On Tuesday, US forces struck more Iranian targets around the Strait of Hormuz, in the biggest outbreak of fighting since July.

The US military's Central Command said it struck Islamic Revolutionary Guard Corps air defences, radar systems, maritime assets, mine-laying capabilities and communications sites on Tuesday. Iran responded by saying it had struck US assets in Bahrain, Jordan, Kuwait and Iraq, while declaring its aim was to drive American forces out of the network of military bases maintained across the Middle East.

Trump threatened on Tuesday to escalate the conflict if Iran hits back against the latest US strikes. In a post on Truth Social, he wrote: "If the failed Nation of Iran retaliates for this very justified attack, they will be hit again at a much harder and higher level, but it will not be the biggest attack of them all, that is waiting in the wings."

Military and political pressures

President Trump's approval rating has fallen from 40% to 33% since the conflict began, according to Reuters/Ipsos polling.

Reuters reported in August that the military had used "virtually all" of its supply of certain precision missiles. On August 30, the Washington Post reported that the heads of the Army, Navy and Air Force warned Pentagon chief Pete Hegseth in a written assessment that prolonging the war was unsustainable and would reduce military readiness in other theatres.

White House spokeswoman Olivia Wales said: "President Trump has destroyed Iran's military capabilities and is crippling what's left of its abysmal economy with the most powerful naval blockade in world history and crushing sanctions."

Vice-President JD Vance and Secretary of State Marco Rubio are among the senior Trump aides who support trying to keep the conflict relatively "quiet" until November, according to two White House officials.

On August 30, Treasury Secretary Scott Bessent said the pressure campaign may cause Iran to lash out militarily, raising the prospect of economic measures contributing to further escalation.

China has not joined Washington's bid to isolate Iran, raising questions about the effectiveness of the campaign, according to a report by The Times of India.

The US has threatened to slap countries that trade with Iran with massive sanctions while maintaining its own blockade on the Strait of Hormuz. America's Gulf allies roundly urged the White House to deescalate after a recent round of attacks in late July, regional diplomats said.

Trump has publicly said the upcoming elections were not factoring into this Iran strategy.
