Myth or truth? An analyses over North Korean nuclear deterrence capability and the real policy of the USA about Northeast Asia

The fear of nuclear North Korea has been a serious problem for the world since 2006 when they exploded their nuclear weapon. Although North Korea always considers their nuclear weapon is for protection of their home-land, USA and its allies in the Far-East Asia thinks the other way. Only China seems to be close to North Korea. China and Russia have always been close allies for North Korea and USA has fought to de-nuclearize North Korea given that North Korea has the capability to strike against USA and her allies by using nuclear weapons and ballistic missiles. Given that USA has deployed THAAD system in Japan and South Korea against North Korean nuclear thread, South Korea and Japan enjoys the US military protection. The probability of a nuclear war has been a perennial fear among the states. After the nuclear bombings of Nagasaki and Hiroshima at the end of WW2, states have started to act more meticulous about nuclear arming and development of nuclear power. Among the states, North Korea has been seen as an enemy nuclear state by USA and its allies given that North Korea has the ability to start an unwanted nuclear war. But there will be severe consequences if a nuclear war breaks out. Therefore, not a single state in the world would want to be the cause of a nuclear destruction.
