Comment about a US intellligence official saying that it was impossible to "denuclearise " the DPRK

No one should blame the Democratic People's Republic of Korea for building nuclear weapons to defend themselves from US aggression . It is the US has twice used nuclear weapons against a non-nuclear state . The US has carried out the highest number of nuclear tests in the world and has the biggest nuclear stockpile in the world. It keeps 1,000 nuclear weapons in south Korea .It has considered using nuclear weapons against the DPRK in the 1950s, in 1968, 1969 and 1976.
It is not "paranoia" . The DPRK was invaded by the US in 1950 and the country ravaged by US bombers. Today the US is reinforcing its troops in south Korea . The DPRK not only faces a threat from the US but also from its former colonial occupier Japan which is rapidly becoming a military giant.Japan is not a pacifist state, it would like to revive the Japanese empire with the backing of the US. Other imperialist countries such as the UK are becoming militarily involved in south Korea. Thus the DPRK faces a massive threat from US and world imperialism.
I was in at the DPRK at the time of the 5th nuclear test and also the successful road launched ICBM test.
The Songun policy of the DPRK is absolutely correct . Respected Marshal Kim Jong Un is a wise and farsighted leader who is pursuing the policy of building the nuclear force and economy in parallel. I could see that this policy is successful as there are new buildings springing up in the DPRK and living standards are rising . Moreover I believe that the DPRK will win the Cold War that the Soviet Union lost (or actually surrendered )
