The president of the Russian National Research Center, Kurchatov Institute, Mikhail Kovalchuk said. He said at the Russian wine making forum in Moscow, nuclear weapons will not be used by anyone, only if to destroy humanity. This type of weapon is a deterrent Kovalchuk recalled. He noted that it will never occur to anyone, except for the United States to use it. Kovalchuk stressed it is the bottom line weapon. It is a weapon that frightens but should never be used. While commenting on the global threats facing humanity, he noted that the risk of human race being destroyed by biological means was much greater. Imagine this COVID will suddenly show a 5-fold, 10-fold increase in mortality, who will survive in these conditions, only the country that has the know-how to create a vaccine. We were the first to do that. We created several vaccines. Several other countries did that too. The other countries will be doomed to extinction if nobody supplies a vaccine to them. He added that the national security and technological independence of states primarily depended on agriculture, medicines, and the biosecurity of the population as a whole.
