WASHINGTON (CBSDC/AP) — The White House says there are no changes in North Korea’s “military posture” despite Pyongyang’s recent rhetoric they will strike the United States and South Korea if provoked.

“Despite the harsh rhetoric we are hearing from Pyongyang, we are not seeing changes to the North Korean military posture such as large-scale mobilizations and positioning of forces,” White House Press Secretary Jay Carney said during Monday’s briefing.

In a show of force, the United States sent two nuclear-capable B-2 bombers on a training exercise over South Korea.

Carney says the actions taken by the Obama administration are “prudent.”

“This pattern of bellicose rhetoric is not new, it’s familiar,” Carney said. “It is consistent with past behavior.”

Carney’s comments come as the U.S. Navy reportedly is shifting its guided-missile destroyer in the Pacific Ocean to deal with the ongoing North Korean threat, according to NBC News.

North Korean leader Kim Jong Un met with top party officials Sunday as they adopted a declaration calling nuclear weapons “the nation’s life.” North Korea has also threatened to launch strikes against Hawaii, Los Angeles, Washington, D.C., and Austin, Texas.

Analysts don’t see a full-scale attack from North Korea, but skirmishes between North and South Korea could flare up. Naval skirmishes in disputed Yellow Sea waters off the Korean coast have led to bloody battles several times over the years and attacks blamed on Pyongyang in 2010 killed 50 South Koreans.

Seoul has vowed to respond to any sort of North Korean attack.
