Pentagon awaiting Trump order to resume strikes on Iran

BLUFRenewed U.S. strikes on Iran are likely before the end of May, with force posture and intensified coordination with Israel signaling Trump has effectively abandoned the diplomatic track.

Pentagon officials are awaiting a presidential order to resume strikes against Iran, previously conducted under Operation Epic Fury and paused during a ceasefire, following Trump's return from Beijing, where he posted an AI-generated image on Truth Social with the caption 'This was the calm before the storm.' Over 50,000 U.S. troops, two aircraft carriers, and more than a dozen destroyers remain postured in the region for immediate resumption; CBS News reports Trump has discussed a timeline as soon as this weekend. The U.S. and Israel are conducting their most intensive strike-coordination sessions since the ceasefire, with potential targets including Iran's nuclear material at the Isfahan site. NBC News reports the Pentagon is considering renaming the operation 'Sledgehammer' if the ceasefire collapses.

Analysis
Renewed strikes on Iran are likely by May 31, corroborated across CNN, CBS, and NBC. Current military posture exceeds pre-Epic Fury levels, Trump has publicly rejected Tehran's latest proposal, and U.S.-Israel strike coordination is at its most intensive since the ceasefire began. A contemplated rename to Operation Sledgehammer, should the ceasefire collapse, would restart the War Powers Resolution clock and preempt a congressional authorization fight. The signaling may instead be primarily coercive leverage aimed at last-minute Iranian concessions, with no resumed combat required. If strikes resume within the forecast window, allied governments must shift immediately to military contingency postures. If Trump holds, Congress retains leverage to demand formal authorization before a new 60-day clock begins.
