Recently there's been a lot of debate about whether or not the UK should replaced Trident or just abandon nuclear when the system becomes obsolete. This week's news should, I hope, make the case for multi-lateralism absolutely clear.
No-one wants a nuclear war, but the idea of unilaterally disarming and leaving nuclear weapons in the control of states such as North Korea is a worrying thought. Many have made the case that the problems the world faces today stem from terrorism, against whom nuclear weapons are not much use. But our ancestors in the nineteenth century probably thought Europe was stable and that armies and weapons for grandscale wars were a thing of the past. The geopolitical situation is in constant flux. Today is a reminder of the power rogue states can yield.
I hope that this doubles the resolve to replace Trident.
