Taking weeks of shrill rhetoric and threats to a fresh high on Tuesday, North Korea announced plans to restart a shuttered plutonium reactor and increase production of enriched uranium. So did we just move one step closer to nuclear armageddon? Here’s a reading list of comment and analysis to help gauge the hazard level.

  • Our own Gideon Rachman argues that there is still “an unfortunate tendency in the west” to treat North Korea as a bit of a joke. “In reality, the Pyongyang regime is about as unfunny as it gets.” He warns that the US and South Korea are responding to North Korea as if it is a rational adversary – “but the unsettling reality is that we cannot be sure.”

The big headline from the report (the worrying news, if you like) was that Iran has significantly increased the number of centrifuge machines which can be used to manufacture more highly enriched uranium – so-called 20 per cent uranium – at its heavily protected facility at Fordow, near Qom. This 20 per cent concentration worries the west because it is close to the weapons grade concentration of uranium needed to produce bomb. Read more

In recent years Iran has reacted to most UN inspectors’ reports with relief. Even critical assessments and condemnations of its lack of cooperation were met with delusional statements insisting that so long as the International Atomic Energy Association found no evidence of a weapons dimension to the nuclear programme Tehran was in the clear. Read more
