 Russia threatens the world with nuclear weapons again. What deputy chairman of the Russian Security Council, Dmitry Medvedev, said about nuclear powers involvement in conflicts is fully in line with Russia's nuclear doctrine, Kremlin spokesman Dmitry Peskov noted. Earlier, Medvedev wrote a post on Telegram, commenting on statements made at the World Economic Forum in Davos, that Russia must lose in Ukraine. According to the deputy chair of the Russian Security Council, nuclear powers don't lose in major conflicts on which their future depends, and it should be clear to any Western politician. It doesn't occur to Western politicians to draw the most obvious conclusion that a nuclear power's defeat in a conventional war may trigger a nuclear one. Nuclear powers have never lost major conflicts that their future depends on. Medvedev pointed out. Medvedev, a top ally of President Vladimir Putin, said that Western allies should understand the risks of increasing supplying powerful military equipment to Kiev and that the defeat of a nuclear power in a conventional war could trigger a nuclear war. Asked about Medvedev's comments, Kremlin spokesman Dmitry Peskov said the remarks were in line with Russia's nuclear doctrine, which states that after aggression against the Russian Federation with conventional weapons, when the very existence of the state is threatened, read the nuclear doctrine. There is no contradiction there. Peskov stressed. Putin and other Russian officials have repeatedly used high alerts and hints at a readiness to aim or use nuclear weapons since their invasion of Ukraine began.
