As diplomats scrambled in Islamabad and a fragile ceasefire teetered on the edge of expiry, Iran sent a very different kind of message through the streets of Tehran-rolling out its most formidable ballistic missile, the Khorramshahr-4, at pro-government rallies across Revolution Square and Vanak Square in a deliberate show of defiance. Known also as the Kheibar, the liquid-fueled medium-range missile carries a warhead of up to 1,800 kilograms and has a range of 2,000 kilometres, putting Israel, Saudi Arabia, and parts of NATO's eastern flank well within reach. With a payload capacity that meets theoretical thresholds for nuclear-capable delivery, its appearance on the streets of Tehran was anything but ceremonial-it was a calculated signal to Washington that Iran's strategic deterrent remains very much intact despite the punishment delivered by US-led Operation Epic Fury targeting its missile and nuclear facilities. The IRGC has described the Khorramshahr-4 as one of the main pillars of Iran's active deterrence, and its public display hours before the ceasefire deadline underscored Tehran's dual-track approach-keeping the door to negotiations technically ajar while making unmistakably clear that it retains the military capability and the will to resume hostilities on its own terms. President Trump, for his part, extended the ceasefire indefinitely on April 21st, but Iran's foreign ministry dismissed US statements on talks as a media game-leaving the world in an unnerving limbo, with oil prices crossing a hundred dollars a barrel, the Strait of Hormuz still under naval blockade, and a missile that has already been fired at Tel Aviv now parading through the Iranian capital as the clock continues to tick.
