The U.S. was just hours away from beginning military strikes against Iran, before President Trump reportedly pulled the plug on the operation.

The intended targets of the strikes, which were recommended by the Defense Department, would have included radars and missile batteries. Top military brass and diplomats were expecting the attack until the operation was called off around 7:30 p.m. Thursday night. Planes were already in the air and ships were readying for the escalation, but no missiles were ever fired.
