The North Korean rocket launch a week ago produced a predictable wave of diplomatic indignation. The United Nations Security Council held an emergency session, where diplomats from the US and its allies pressed for “strong condemnation”. There was no shortage of stern warnings coming from capitals worldwide. This diplomatic outburst seems to be a normal reaction. President Barack Obama, condemning the launch, said: “Words must mean something.” Indeed. However, the words of condemnation mean nothing.

The US and its allies have almost no leverage when it comes to dealing with North Korea. There is much talk about sanctions, but, to be effective, they must be upheld by all major states, and this is not going to happen. China and Russia, driven by their own agendas, have already made clear that they would not support a tougher approach. These two states have veto power in the Security Council, and are major trade partners of North Korea (slightly more than half of Pyongyang’s entire trade is with them).
