South Korea, Japan, And US Will Pressure North Korea Into Denuclearization

"South Korea, the US and Japan agreed to further strengthen joint efforts aimed at making North Korea have no choice but to step forward toward meaningful denuclearization," said South Korean Vice Minister Lim Sung-nam in a press conference with US Deputy Secretary of State Antony Blinken and Japanese Vice Foreign Minister Shinsuke Sugiyama. The talk between the three representative of the participating nations was held after the Communist leader Kim Jong-Un said in his New Year's speech that they are close to finishing a perfect missile and are getting ready for a test-fire.

Stated in the joint fact sheet the parties had agreed on, the "complete, verifiable and irreversible denuclearization of North Korea remains the only viable option to safeguard peace and security. North Korea's provocations only serve to deepen its isolation."

Trump Tweet Shows Lack Of Understanding, Says Expert

Meanwhile, President-elect Donald Trump recent tweet about North Korea's provocation received a lot of critics. He recognizes the issue as a priority, however, it also shows how he lacks understanding of its seriousness, according to experts.

White House Press Secretary Sean Spicer said that the tweet means President Trump will "make sure that it won't happen" under his watch.

"Trump will soon learn that he can't just tweet away North Korea's ICBM and nuclear programs. He is flat out wrong about North Korea not developing a nuclear weapon that can reach the U.S. The only question is when. But it is likely to acquire that capability during his first term," said senior analyst at the Atlantic Council, Robert Manning.
