Iran has intensified its military posture after Donald Trump rejected Tehran’s latest response to a U.S. peace proposal, calling it “totally unacceptable” and “a piece of garbage.” Hours later, the IRGC launched massive “Martyred Commander” war drills around Tehran, declaring full combat readiness against the “American-Zionist enemy.” Iran also expanded its claimed operational zone in the Strait of Hormuz, warning it would “teach a lesson” to any aggressor. The escalating rhetoric and military activity have raised fears of a wider regional conflict involving the U.S., Israel, and Gulf allies as tensions continue to surge across the Middle East.
