U.S. National Security Adviser John Bolton has urged North Korea to make the first move to dismantle its nuclear weapons program, saying the U.S. has no interest in lengthy talks.  

Bolton told Fox News on Wednesday that the U.S. would like to move quickly and if North Korea is serious, it should want to move quickly too.

He added that North Korea is facing a "decisive and dramatic choice" on whether to give up its weapons programs and ballistic missiles but the U.S. will find out soon because diplomatic engagement will proceed very quickly. 

President Donald Trump's security adviser also said that until North Korea takes "palpable, concrete" steps toward denuclearization, all sanctions will remain in force.
