Stockpiling nuclear weapons? That will do nothing for national security, Keir Starmer | Jeremy Corbyn

Until the UK and other nuclear states are brave enough to disarm, the Doomsday Clock will keep ticking towards midnight

Seventy-seven years ago, a group of scientists created a symbolic Doomsday Clock to measure humanity's proximity to self-destruction, or midnight". The hands move closer to - or further away from - midnight, depending on what existential threats exist at that particular time. Addressing the UN general assembly last year, the UN secretary-general, Antonio Guterres, announced that the clock had moved to 90 seconds to midnight, declaring that humanity was perilously close to catastrophe. This is the closest the clock has ever stood to humanity's darkest hour," he said. We need to wake up - and get to work." Guterres named three perilous challenges. One, extreme poverty. Two, an accelerating climate crisis. And three, global nuclear war.

Lie flat in a ditch and cover the exposed skin of the head and hands." In 1980, Margaret Thatcher's government published a pamphlet, Protect and Survive, advising people what to do in the event of a nuclear attack. In what was in essence a DIY handbook, people were instructed to hide under a table, place bodies of dead relatives in another room or, if outside, lie on the floor and hope for the best. Adopting an optimistic attitude toward our extinction, the 32-page booklet was ridiculed by a population that knew there was no survival kit for nuclear annihilation.

The government no longer distributes booklets that advise us how to survive nuclear war. Instead, it buries its head in the sand entirely, turning a blind eye to the fact that we are getting closer and closer to midnight. After a period of gradual decline that followed the end of the cold war, the number of operational nuclear weapons has risen again. There are now more than 12,500 warheads around the world, with 90% belonging to Russia and the United States alone.
