US and Israeli airstrikes against Iranian military sites and infrastructure persist into March 31, with recent US B-52 deployments and a strike on Isfahan generating visible fireballs, as confirmed by Pentagon updates. Defense Secretary Pete Hegseth described the coming days as "decisive" amid ongoing degradation of Iran's missile capabilities, while President Trump told NBC News operations are "coming to an end" without announcing a ceasefire. Absent verifiable cessation of attacks on Iranian soil per market rules—now day 32 since February 28 launch—traders price 100% consensus for continuation through March 31. A sudden diplomatic breakthrough or no-strike declaration could challenge this, though Tehran vows retaliation until victory.
