Three weeks after joint US–Israeli strikes began on 28 February 2026, the campaign has entered a volatile fourth week. On Saturday night, President Donald Trump warned he would order strikes on Iranian power plants unless Tehran “fully” opens the Strait of Hormuz within 48 hours, elevating the risk of direct hits on civilian energy infrastructure.

The public messaging and the military picture remain at odds. While Mr Trump has said operations are “very close” to complete and has floated a “winding down,” the Pentagon has moved additional Marines and warships into theatre and sustained daily strikes on Iranian targets. (apnews.com)
In a detailed Truth Social post, the president set out current military objectives: degrade Iran’s missile forces and defence industrial base; eliminate elements of its navy and air force; prevent any path to a nuclear weapon; and protect regional partners. Notably absent was a commitment to reopen Hormuz; Mr Trump wrote that countries reliant on Gulf oil should “guard and police” the strait rather than the United States. (axios.com)
The shift is stark when set against early‑war rhetoric. References to “unconditional surrender” and to choosing Iran’s next leader-which appeared in the opening days-have fallen away from recent statements, replaced by narrower military aims. (time.com)
Hormuz policy now drives the strategic debate. The strait ordinarily carries roughly one‑fifth of the world’s crude shipped by sea and a significant share of LNG; since early March, commercial transits have collapsed, with insurers curbing cover and freight costs surging. Limited sailings continue, including movements by sanctioned or “shadow fleet” vessels. (apnews.com)
The geographic scope of the confrontation has widened. Iran has attempted to strike the joint US–UK base at Diego Garcia; the missiles failed to hit, but London has now permitted US bomber operations from British bases after initial hesitation. (apnews.com)
Force posture is tightening around the Gulf. The United States is sending an amphibious assault ship and roughly 2,500 Marines from Japan toward the Middle East, with a second Marine force and ships departing California and expected from mid‑April, according to allied and US reporting. (axios.com)
Advisers and analysts have floated a limited ground move focused on Kharg Island, Iran’s primary oil export terminal. Seizing or blockading the site could pressure Tehran by constraining exports, but would carry high escalation and market risks; the US has already bombed military targets on the island. (axios.com)
Tehran has signalled that any US strike on Iranian energy facilities will trigger attacks on American and Israeli energy and infrastructure assets across the region, underscoring the potential for a rapid cycle of retaliation against critical sites. (apnews.com)
Financing and authorisation questions are coming to the fore. The Pentagon is preparing to seek about $200bn in emergency funding, indicating operations are not ending imminently; early reaction on Capitol Hill-including from Republicans-has pressed for clarity on objectives, timelines and any path to ground operations.

Under US law, the War Powers Resolution clock began with the administration’s 2 March notification to Congress. Without new statutory authorisation, the 60‑day limit falls on 28 April 2026 (with a further 30‑day withdrawal period). The House and Senate have so far declined to curtail the president’s actions, rejecting war‑powers measures earlier this month. (warpowers.lawandsecurity.org)
Economic effects are already visible. US retail fuel prices have hit their highest since 2023 as benchmarks swing with supply risk; Asia-taking the bulk of Hormuz crude and LNG-is the most exposed to sustained disruption. (apnews.com)
Key watch points for policy teams: whether Iran permits broader commercial transits through Hormuz before late on Monday, 23 March; whether Washington acts on its threat to hit Iran’s power grid; and whether allies convert political support into naval assets for an escort mission-most have so far offered statements rather than ships.
