Why North Korea is important for U.S?

Supposedly, I heard some news about Kim Ju-Un , who is a leader of North Korea tried to transform gradually deal with South Korea and U.S. Unlike former leader, Kim has abnormal thought on political behavior. So, now currently, according to some meeting with China and South Korea , is might be fake or political reformation for civil ? It is very interested , we all have to wait the results of US- North Korea meeting and responses of Russia and China.

Donald Trump accepts invitation to meet North Korea's Kim Jung-un. Most of politicians think that that is the great meeting between US and North Korea. Some of politicians think it might be political illusions. Anyway, most of countries like Japan , South Korea and some ASEAN countries hope that it would be the great time after meeting. What are your thoughts on this case? Please share !!

At the moment, North Korea poses an existential threat to every U.S. citizen with an Iranian backed nuclear ICBM program and this needs to be clearly emphasized when addressing the public. Violence and the use of nuclear weapons however is not the answer. There are a plethora of more sanctions the U.S. can impose on not only China but anybody doing business with the North Korean regime. In Sean Hannity's podcast he states that "we have the means to decapitate the regime without using a singular nuclear weapon" and this is very true. U.S. satellite images have been able to spot ships transporting oil and other essential things for the regime to function. The U.S. should clearly express that anybody that does business with North Korea cannot do business with the United States. This would be exceedingly effective as many corporations, businesses, and people rely on business with the United States to see continued sucess. More specifically, the banking system among many other sectors can simply not afford to lose American business and will therefore cease all activity with North Korea. The U.S. is not powerless in regards to this issue. The U.S. has yet to even scratch the surface with regards to sanctions and other resources exerted to prevent the North Korean's from continuing their Nuclear program. The U.S. can stop being a paper lion without resorting to nuclear weapons or any other sort of violence.
