The good news is the clock has not been moved any closer to midnight. The bad news there are only two minutes to go, which is as close as they put it at any point during the cold war. The reasons they give are climate change and, yes, good old nuclear weapons.

In the nuclear realm, the United States abandoned the Iran nuclear deal and announced it would withdraw from the Intermediate-range Nuclear Forces Treaty (INF), grave steps towards a complete dismantlement of the global arms control process. Although the United States and North Korea moved away from the bellicose rhetoric of 2017, the urgent North Korean nuclear dilemma remains unresolved. Meanwhile, the world’s nuclear nations proceeded with programs of “nuclear modernization” that are all but indistinguishable from a worldwide arms race, and the military doctrines of Russia and the United States have increasingly eroded the long-held taboo against the use of nuclear weapons.
