North Korea threatened a nuclear attack on The United States for endorsing stepped up United Nation Sanctions against them for their persistent development of a nuclear warhead. They also said that they would back out of the 1958 cease-fire with South Korea, effectively reinstating the War there. These threats only go to show the irresponsible behavior that persists within this country that allows its people to starve to death so the few that are rich can live in royal luxury. It is indeed a sad commentary .
Even China has joined in the economic sanctions and wants to be assured that they are being delivered in such a manner as to assure pressure on the N.C. The Chinese endorsement of sanctions is more evidence of the growing frustration of the North Koreans closest friend in the area. But the continued irresponsible threats are threatening the stability of the entire region. China does not a war during their economic good times. It serves them well to express their discontent as well.
However, it is thought that the North Koreans who have nuclear capability are not yet able to deliver a nuclear warhead to The United States. U.S. Government Officials have made it clear that they could counter any such attempt. However, I would think that the escalation of hostilities against South Korea is a larger concern to the U.S.
The situation of course bares watching. If North Korea were attack the South then that would certainly paint a whole new picture on this on again….off again issue with North Korea.
