UPDATE — this extends our earlier coverage: Trump declares Iran ceasefire dead, threatens fresh strikes as markets brace for Hormuz

What was a threat 24 hours ago is now a sustained air campaign: the United States struck Iran for a second consecutive day on Wednesday, Tehran answered that it has "no red lines", and oil prices are climbing. Our earlier piece covered the opening round — President Trump declaring the ceasefire "over" after Iranian attacks on shipping in the Strait of Hormuz — and markets bracing for disruption.

Day two of strikes

  • Trump ordered a fresh round of airstrikes on Wednesday, a day after US forces hit more than 80 targets, the New York Post reports; he has called the ceasefire "over" for what he termed a "sick" regime.
  • U.S. Central Command says the additional strikes are meant to "further degrade" Iran's ability to disrupt maritime traffic, and came hours after Trump threatened a "big attack", per The Hill.
  • Trump declared the ceasefire ended while speaking at the NATO summit in Turkey, The Hill reports.

Tehran's answer: "no red lines"

  • An Iranian official warned on Wednesday that Iran has "no red lines" when it comes to its defense, The Hill reports.
  • The warning was addressed to "the Gulf states that have stood alongside Trump" in the conflict, per the same report — a message to Washington's regional hosts, not just to Washington.
  • None of the sources records any active diplomatic channel; whether one still exists is an open question.

Oil and markets

  • The ceasefire's end is driving oil prices higher and fueling uncertainty over future energy prices, per The Hill.
  • Washington frames both days of strikes as retaliation for Iranian attacks on three commercial ships in the Strait of Hormuz, according to the same report.

The bigger picture

The escalation ladder has moved three rungs in under a week: Iranian attacks on commercial shipping, then an 80-plus-target US strike paired with the ceasefire's declared death, now a second consecutive day of bombing with an open-ended CENTCOM mandate to keep degrading Iranian capabilities. Foreign Policy was still asking whether the ceasefire is over; Wednesday's strikes answer that in practice. The venue of Trump's declaration — a NATO summit — puts allies on notice that this is now alliance-relevant, not a bilateral spat.

HYPOTHESIS: Tehran's "no red lines" message, aimed explicitly at Gulf states, is a threat to widen targeting beyond shipping — to Gulf infrastructure and the US bases those states host — in order to raise the cost of a sustained US campaign. Supporting this: the warning names the Gulf states aligned with Trump (The Hill), and Iran's escalation so far has targeted commercial shipping rather than US forces directly. Against this: the sources record no strike on Gulf territory, and the line may be deterrent rhetoric. Evidence strength: circumstantial.

What to watch

  • Whether Iran acts on the "no red lines" warning against Gulf-state territory or US bases in the region.
  • Whether the US target set expands beyond maritime-disruption capabilities, CENTCOM's stated aim so far.
  • Oil prices and shipping behavior in the Strait of Hormuz as the campaign continues.
  • Whether any mediator — Gulf states, NATO allies, or Turkey as summit host — opens a channel between Washington and Tehran.
