On March 14, two Russian fighter jets intercepted a U.S. Air Force MQ-9 Reaper in international airspace, breaking one of the drone’s propellers and forcing it to crash into the Black Sea. The Russians probably understood that U.S. military retaliation – or, more importantly, escalation – was unlikely; wrecking a drone is not like killing people.
