The Short Version
The claim is largely accurate. Joe Kent served as Director of the U.S. National Counterterrorism Center, and he resigned in mid-March 2026 citing opposition to the ongoing U.S.-Israel war on Iran. His authenticated resignation letter confirms this. Two caveats: the phrase "U.S. and Israel's war" slightly simplifies Kent's emphasis on U.S. involvement driven by Israeli pressure, and CBS News reports Kent was already under FBI investigation for alleged classified leaks before resigning — context the claim omits.
