On March 29, according to The Washington Post, U.S. officials stated that the Pentagon is preparing for weeks-long ground operations in Iran. With thousands of U.S. soldiers and Marines arriving in the Middle East, this could mark a dangerous new phase of the war if President Trump chooses to escalate. Any potential ground operation would not be a full-scale invasion but could involve joint raids by special operations forces and conventional infantry units. Such a mission could expose U.S. personnel to a range of threats, including Iranian drones and missiles, ground fire, and improvised explosive devices. As of Saturday, it remained unclear whether Trump would approve or reject all or part of the Pentagon's plans. According to PolyBeats monitoring, the probability of U.S. troops entering Iran before the end of this month on the prediction market Polymarket is 11%, and the probability before the end of April is 62%.
