The U.S. is demanding that Tehran restrict its missile program as part of a deal to avert new clashes, but it has so far refused

Iran’s missile program was born of weakness in the early years of the Islamic Republic. Now the question is whether it is formidable enough to head off a military confrontation with President Trump.

Tehran unleashed a barrage of around 500 missiles that struck civilian and military locations in Israel last June but did little strategic damage. Though Israel pounded Iran’s missile launchers and storage sites during a 12-day war in June, the regime emerged from the bruising conflict with much of its remaining arsenal intact.
