North Korea nuclear testing

The region is inching "closer to the threshold of nuclear conflict," Pyongyang said on Monday.

Retired Navy Admiral Mike Mullen warned that the U.S. is in a "more dangerous position" as North Korea missile tests have reached an all-time high.

The nuclear-powered, 100,000 ton aircraft carrier USS Ronald Reagan participated in the three-day exercises.

It comes amid signs North Korea could resume nuclear weapons testing for the first time since 2017.

If the U.S. wants North Korea to cease and desist from missile tests, it needs to have the fortitude to negotiate a cap on them.

"We can move very quickly" on weapons dismantlement, national security adviser John Bolton told CBS News.

He also contradicted his national security adviser John Bolton.

North Korean officials slammed claims that Trump was the reason the country was coming to the negotiating table.

"One of the clear reasons North Korea wants to talk to America now is that it feels it is working from a position of strength," an expert told Newsweek.

Satellite images show that a key 5-megawatt reactor in North Korea is operational.

Pyongyang also said it would not need nuclear weapons if it received a security guarantee.

The move is an attempt to squeeze Pyongyang's use of seagoing trade to feed its nuclear missile program.

"North Korea may now be only months away from the capability to strike the United States with nuclear-armed ballistic missiles," U.S. envoy Robert Wood said.

An East Asia scholar suggested in a tongue-in-cheek editorial that Trump should consider targeting the North Korean leader's porcelain throne as a way of scaring the crap out of the dictator.

The U.S. has the most powerful military in the world.

North Korea analysts said the next threat could come from underwater.

North Korea refused to give up its nuclear weapons.

North Korea is believed to have anywhere from 25 to 60 nuclear weapons.

"Look at the regime, the hostility of this regime to the whole world," the national security adviser said.

News of Park's alleged execution follows reports that North Korea's second most powerful official after leader Kim Jong Un has been punished.

North Korea is making major strides with its nuclear program.

The South and North Development (SAND) research institute reported the situation in a village near the Punggye-ri nuclear facility.

Defectors claim that 80 percent of trees planted near the test site die, that underground wells have been evaporated and that babies in the region are born with birth defects at alarming rates.

Increased activity observed around Pyongyang's missile research facility could indicate preparations for a new test.

The Punngye-ri underground facility hosted the country's sixth and most powerful nuclear test to date.

South Korean and Chinese scientists worry that a collapse at the mountain could trigger a radiation leak.

"We decided to release the manga after hearing from our residents that the current manual is hard to understand," a Hokkaido official said.

Analysts say North Korea may have to move on to other tunnel testing sites or build new ones.

Pyongyang's deputy ambassador spoke to the U.N. General Assembly committee for disarmament, but skipped the most inflammatory parts of his statement.

Doing more of the same with China—cajoling it to help while threatening to punish its companies that do business with Pyongyang—isn't working.
