The deaths of three US servicemembers over a 24-hour period this weekend have raised concerns in Washington that President Donald Trump could press for further escalation in the war involving Iran, even as both sides signal they are keeping diplomatic channels open.

The servicemembers’ deaths increased the US death toll in the conflict to 17 since fighting began in March. The Pentagon said on Monday that since US Central Command (Centcom) began daily waves of strikes against Iran on 7 July, nearly 100 service members in the command’s area of responsibility have been wounded. Of those injured, it said 96% have returned to duty.

Vali Nasr, a professor of international affairs at Johns Hopkins University, said the exchange of blows changes the political calculations facing Trump. In an interview with The Hill, he said the immediate impact on US personnel could create pressure for a broader response if further casualties occur, or if a US ship is attacked.

Victoria Coates, Trump’s former national security adviser, said the deaths marked “a new phase” and pointed to the “sobering” nature of the events. She said the Iranian leadership appeared increasingly desperate while adding that the United States should treat the situation as serious.

Strikes follow servicemembers’ deaths

The Trump administration responded to the deaths by carrying out strikes over the weekend on Iranian military command centres, air defence and coastal surveillance sites, maritime capabilities, missile and drone launch sites, and communications networks.

In a TruthSocial post on Monday, Trump warned that Iran would “pay” multiple times for killing an American servicemember. White House press secretary Karoline Leavitt said Trump would attend the dignified transfer of the fallen service members at Dover Air Force Base.

Michael Rubin, a Pentagon official during the second George W. Bush administration, said fatalities were an expected consequence of war while also noting that the deaths could provide impetus for those urging a response.

A White House official told The Hill that Trump is focused on ensuring Iran pays for what Washington described as violations of a memorandum of understanding and for “acts of terrorism” in the Strait of Hormuz.

Diplomacy remains open, both sides say

Despite the intensified military campaign, senior figures on both sides indicated that diplomacy was still possible. US Secretary of State Marco Rubio said over the weekend that talks with Iran remained open and would continue if Iran showed that the channel could work. He spoke at Joint Base Andrews.

Iran’s Foreign Ministry spokesman Esmail Baghaei said on Monday that the two countries were continuing to exchange messages through mediators. He said diplomatic efforts had remained active in recent days and that ideas had been conveyed without providing further details.

US forces have continued strikes for a 10th consecutive day since a fragile ceasefire broke down. Centcom said the attacks included strikes from coastal surveillance and air defence facilities, maritime capability targets, missile and drone storage sites, underground weapons storage locations, bridges and other infrastructure.

Iran said it has retaliated against at least four countries in the region, targeting US positions in Qatar, Bahrain, Kuwait and Jordan. Kuwait’s military said its forces were working on intercepting Iranian munitions. A Jordanian state broadcaster reported that Jordan intercepted three incoming Iranian missiles on Monday.

Coates said Iran’s ability to target US forces in the region has been degraded since the war began earlier this year, citing a decline from “well over a hundred” missile launches at the start to single digits per day. She said the trend would likely worsen for Iran.

Nasr said the United States appeared prepared for a long campaign but added that economic pressure could prompt another truce. He also cautioned that escalation could still occur regardless of US intent.

Hormuz blockade and public concern

Beyond air and maritime strikes, the US has sought to squeeze Iran’s economy by resuming a naval blockade in the Strait of Hormuz. Centcom said on Monday that it redirected seven commercial vessels and disabled one ship to prevent it from entering an Iranian port.

Nasr said that while the US could impose costs, breaking Iran’s hold on the strait would likely require a far larger conflict, given Tehran’s ability to raise risks for ship owners and insurers with limited attacks.

The renewed hostilities have also pushed gas prices back to about $4 a gallon. A Washington Post-Ipsos poll released last week found that only one in four voters expect Trump’s negotiations with Iran to produce a better deal than the agreement reached during the Obama administration. It also reported that majorities of Americans were not confident talks would reduce gas prices or prevent Iran from acquiring a nuclear weapon.

In the region, Coates highlighted potential diplomatic momentum beyond the Iran conflict. She said Lebanese President Michel Aoun would become the first Lebanese president to meet a US president at the White House on Tuesday to discuss how to disarm Hezbollah, an Iran-backed militant group.

Trump’s hard line with Iran looks like Margaret Thatcher’s Falklands moment: unpopular at home, squeezed by fuel costs and skepticism, but choosing confrontation abroad to claw back ground.

Thatcher’s approval was scraping bottom before the Falklands, but victory reframed her as decisive, the Iron Lady!

Trump’s blockade in Hormuz and strikes on Iranian assets carry the same logic. But if escalation drags on without a clear win, the Thatcher parallel breaks, leaving only fatigue.

Instead of steely resolve, Trump will be seen as nothing more than the Gilded Buffoon.

The Falklands War had nothing to do with her being called the "Iron Lady"!

The nickname "Iron Lady" was given to Margaret Thatcher by the Soviet newspaper Red Star after she delivered a speech on January 19, 1976,
