At 1236 hours local time, North Korea tested another nuclear weapon, its sixth and easily its largest. With a yield of about 100 kilotons, this test was about 5x more powerful than the device dropped on Nagasaki and about 10 times larger than most of their previous tests.
This represents a significant escalation in the game of nuclear brinkmanship that is going on. It means North Korea have a warhead now capable of destroying a city larger than Christchurch or Wellington.
United States President Donald Trump now has a serious problem on his hands. He warned North Korea that it would face fire and fury unlike anything it has seen before if it continued to play the current high risk game of brinkmanship. Today North Korea essentially said to Mr Trump “I dare you to. Go on. I DARE YOU!”.
Neither side will want to be seen to be backing down. The range of options for containing North Korea has failed one option after the other. Probably every single sanction that has been put in place has been ignored by the successive Kim regimes. It has been offered carrot (aid/easing of sanctions/South Korean economic co-operation and so forth), in return for giving up its nuclear weapons programme, enforced by the stick (normally a tightening of sanctions).
The options for President Trump are limited. If he tightens sanctions further, North Korea will most likely simply ignore them and probably test another weapon or continue other provocative acts, such as firing more missiles. The fact that this happened just days after North Korea fired a missile across the northern Japanese island of Hokkaido, triggering civilian warning systems shows that the regime cares not one jot.
Normally there is a rule of thumb that can be applied to this. If the people of South Korea, and in particular Seoul are not worried, then nor should we be. But a missile fired across the island of a sovereign neighbour and now the biggest nuclear test the world has seen since the end of the Cold War might change that.
However one nation holds the key cards in this dangerous game: China. The Peoples Republic can crash the North Korean regime by exerting overwhelming economic and diplomatic pressure if it chooses to. To some extent China needs the regime to survive as much as the regime needs China. Without the North Korean regime there is no buffer between China and the democratic South Korea. China has spent a massive amount of time and resources maintaining its regime and has an appalling human rights record, perhaps only exceeded by North Korea. But China’s economy could not survive without its huge trade with the United States. Thus increasingly China is becoming the nation to watch, perhaps as much as North Korea and the United States.
Here in New Zealand we can do two things:
- Be extremely grateful for the distance between us and the Korean Peninsula
- Vote for a Government that actively encourages all parties to pull their heads in
Other than that, buckle in for a roller coaster ride I don’t think most people want to be on.
