North Korea has confirmed that it conducted its fifth nuclear test on Friday (9 September) and the explosion was deemed to be 5.3 on the Richter scale. Based on preliminary data, experts aver that this could be a nuclear bomb in the 15 to 30 KT (kiloton) bandwidth. It may be recalled that the Hiroshima bomb used by the US on Japan in August 1945 was about 15 KT.
There are many complex regional and global implications of the latest North Korean nuclear test (the first credible nuclear explosion was conducted in October 2006) that involve the major regional powers — the US, China, Russia, Japan and South Korea — and their bi-lateral and multilateral relations.
Some of these strands have a relevance for India, particularly in relation to how Japan and South Korea now perceive their own WMD (weapons of mass destruction) security and the degree to which they feel that the US nuclear umbrella is adequate to assuage the insecurity that a nuclear Pyongyang induces.
