The fear of a war with North Korea continues to grow as daily threats against the United States and South Korea persist.
North Korean leader Kim Jong Un upped the ante Tuesday, vowing to re-start a dormant reactor in the nation's main nuclear facility. The reactor has the ability to produce enough material for one atomic bomb a year.
The reactor was shut down in 2007 as part of international nuclear disarmament talks.
This marks the first time North Korea said the reactor would be used to make nuclear weapons. When it was first unveiled, the North insisted it was meant to generate electricity.
Even with this latest round of threats, White House officials say there's no evidence that Kim will actually act.
"Despite the harsh rhetoric we're 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.
Meanwhile, the Washington Free Beacon reports China has begun activating troops near the Korean peninsula. China is obligated to defend North Korea under a treaty between the two countries.
The United States is responding to the threats with a show of force, sending stealth B-2 bombers, F-22 fighters, and now a U.S. Navy destroyer to the region.
"We believe this has reduced the chance of miscalculation and provocation," Carney said.
North Korea claims it's working toward nuclear-tipped missiles that can reach the United States. But it's not believed to have the technology at this time.
The Pentagon says while it is taking the North's threats seriously, it's being careful not to overreact and spark a war.
