Protecting against nuclear war

Several design changes could be made to the decision-making process to make it safer, according to Cerf. The first would be to remove the 15-minute response time, which forces a US president to launch on warning. Cerf argues this hair-trigger response procedure is a “relic of the past”, considering that the US would retain a second-strike capability by air and sea even if all its land-based intercontinental ballistic missiles were destroyed.

Cerf also thinks that key decision makers should repeatedly practise emergency drills and analyse their responses to learn from their mistakes. They could also conduct “pre-mortems”, in which they imagine worst-case outcomes and then work backwards to see how they could be avoided. Another tweak would be to appoint one member of the decision-making team to oppose the consensus. Rachel Bronson, president and chief executive of the Bulletin of the Atomic Scientists, which has been warning of the dangers of nuclear war since 1945, hopes that Cerf’s forthcoming film will raise awareness and help nudge the world towards a saner, safer future. “What Moran is doing is very important,” she tells me at the PopTech conference. When it comes to nuclear launch protocols, she adds: “We need to rethink every aspect of this system and push for more time and more engagement and more democracy.”

In November, the Union of Concerned Scientists, another campaigning organisation, wrote to President Joe Biden urging him to revise the nuclear launch protocol. Any launch order should require the consent of two high-level officials in the presidential line of succession, the scientists wrote. “As the risk of nuclear war continues to grow, you have the power to take concrete, immediate steps to build a more stable nuclear weapons system, one that isn’t subject to the whims and questionable judgment of one person alone.”
