It had been four months since U.S. troops were targeted in Iraq and Syria, but a pair of rockets screaming toward the sprawling Al Asad Air Base changed that Monday.

While the Defense Department insists the victims are all in stable condition, top military officials warn that this is a "dangerous escalation" in tensions threatening to spill over into an all-out war.
