Two articles highlight the risk of increasing confrontation between states with nuclear weapons, which could become a nuclear holocaust:
David L. Phillips recently wrote: “Forget talk about ‘re-sets’ in relations; the US is on collision course with two implacable adversaries”. These adversaries are Russia and China. Note that he is currently director of the program on “Peacebuilding and Human Rights” at Columbia University and he served as a senior adviser and foreign affairs expert during the Clinton, Bush and Obama administrations.
Earlier this year, US admiral Charles Richard warned of a real possibility of nuclear war with Russia and China. He heads the US Strategic Command.
