The United States halted nearly two weeks of airstrikes on Iran as diplomacy gained momentum, signaling a shift toward negotiation while keeping military options available if needed. President Trump expressed a preference for a negotiated settlement but warned he could resume heavy action if talks falter, citing concerns over dwindling missile-defense stockpiles. Pentagon and White House aides warned that continuing a major offensive would drain munitions and risk regional security, leading to a recalibration toward diplomacy and economic pressure. Iran and Oman began technical and political talks over the Strait of Hormuz, adding a new channel to regional discussions as Iran-backed Houthis escalated attacks on Red Sea shipping. The pause coincides with broader market and regional fallout, including rising energy prices as Gulf actors reassess outcomes. Officials stressed the situation remains fluid and that the diplomatic path between deterrence and engagement is being explored.
