Three Iranian-controlled islands at the Strait of Hormuz are at the center of escalating conflict, with the U.S. military conducting strikes on Abu Musa and Greater Tunb. President Donald Trump has increased U.S. air strikes on Iran and threatened further escalation, raising concerns about repeating past failed strategies.
The conflict, which has driven up global oil prices and impacted financial markets, intensified after the collapse of an interim ceasefire deal. Iran has signaled it could prompt its Houthi allies in Yemen to close the Bab al-Mandeb strait if Washington strikes Iran's power infrastructure. Trump has considered expanding targets to include energy plants, bridges, and seizing Iran’s Kharg Island oil hub, though some options are deemed unrealistic due to high risks.
Analysts suggest that a major U.S. escalation, short of a ground invasion, is unlikely to force Iran to change course, potentially hardening its position. The unraveling of the interim deal comes as Trump faces pressure to end a war that has impacted the economy and his approval ratings ahead of midterm elections. The core dispute revolves around differing interpretations of the preliminary deal concerning control of the Strait of Hormuz, through which a fifth of global oil shipments pass.
Tehran's recent attacks on commercial shipping triggered the latest U.S. response, including a blockade of Iranian ports. Washington has also revoked a waiver allowing Iran to sell oil internationally. U.S. officials described the strikes as 'shaping operations' to target Iranian military capabilities. Iran has warned of retaliatory strikes on U.S. Gulf allies if escalation continues, while also signaling readiness to widen the war.
