North Korea

The US has been quietly amassing firepower in the Pacific during a lull in tensions with North Korea.

North Korea mocked the United States on Tuesday for a recent mistaken alert that sent Hawaii residents into a panic.

According to sources, McMaster met with officials from South Korea and Japan.

Local officials quickly recognized Saturday's false alarm, but it took about 40 minutes to notify Hawaii residents.

The B-2s join a number of B-1 conventional bombers already deployed on the Pacific island.

If war takes the service to the Korean peninsula, Neller wants Marines to know the daunting challenges they would face.

Mattis said there was little chance North Korea could use Olympics talks as a wedge to set Washington and Seoul at odds.

A North Korean missile launched last April crashed into a town near Pyongyang, possibly causing an explosion and casualties.

The rocket would be outfitted with re-entry capability -- a feat North Korea's last ICBM wasn't able to achieve.
