U.S. President Donald Trump said Monday that the war against Iran could be short-lived, but warned of a harsh military response if Iran disrupts global oil supplies. Trump's comments came as Iran selected a new hard-line supreme leader, Ayatollah Mojtaba Khamenei, raising concerns about the conflict escalating. The war has already led to attacks on oil infrastructure and shipping in the Strait of Hormuz, sending fuel prices soaring. Trump also discussed the conflict with Russian President Vladimir Putin, who suggested ideas for a diplomatic resolution.

Why it matters

The war with Iran has already had major global economic impacts through disruptions to oil and gas supplies. Trump's comments suggest the U.S. may be looking for a quick end to the conflict, but his warning about retaliation if Iran blocks oil shipments raises the risk of further escalation. The selection of the more hardline Khamenei as Iran's new supreme leader also casts doubt on prospects for a diplomatic solution.

The details

Trump told Republican lawmakers the U.S. took a 'little excursion' to the Middle East 'to get rid of some evil' in Iran, and predicted the war would be short-term. However, he warned that if Iran disrupts oil flow through the Strait of Hormuz, the U.S. will hit Iran 'TWENTY TIMES HARDER than they have been hit thus far.' Iran's new supreme leader, Ayatollah Mojtaba Khamenei, is seen as even more hardline than his predecessor, raising concerns about Iran's willingness to compromise. The war has already led to attacks on oil infrastructure, shipping, and civilian targets across the region.

  • The war with Iran started on February 28, 2026.
  • Trump made his comments on Monday, March 10, 2026.
