While North Korea continues to elevate threats against the United States and its allies, the Pentagon has not seen anything "out of the ordinary" around key missile sites, a defense official told CNN on Friday.
But the heightened rhetoric over nuclear attacks, so far unmatched by any actual military moves, has no foreseeable endgame, a second defense official said.
"This could go on for a while, and we could see variations of the rhetoric," the second official said.
North Korean leader Kim Jong Un has approved a plan to put rockets on standby to fire at U.S. targets, including the American mainland and military bases in the Pacific and in South Korea, state media reported Thursday.
