Britain’s new prime minister, Andy Burnham, is already having to make one of his gravest decisions. He has to issue the instructions that he alone gives to the military, setting out the UK response in a doomsday scenario of a nuclear weapons attack on us. He will, as I did two decades ago, sign a piece of paper telling commanders whether or not to retaliate and, if so, whether through targeting civilian conurbations or military sites. These instructions are written down in the aptly named “letter of last resort”.
Now, more than at any time since the 1960s Cuban missile crisis, the European public fears a third world war. With the nuclear Doomsday Clock developed by atomic scientists moving ever closer to midnight, and Japan, South Korea, Saudi Arabia, the UAE, Egypt, Poland and Germany contemplating either acquiring nuclear weapons or siting them on their soil, our world is descending from a rules-based order to a power-based one, where might is deemed right and brute force dominates.
