Since the start of the war, the U.S. has sustained a series of small but deadly attacks – including a fatal shooting at a Texas bar – said to be linked to recent Middle East violence. Then came an Iran-sponsored cyberattack on a Michigan medical equipment company. Last week, reports of unidentified drones flying over Fort McNair, a Washington, D.C., military base where top officials, including Secretary of State Marco Rubio and Defense Secretary Pete Hegseth, live, raised concerns about foreign attacks.
