 Medvedev, response to potential strikes inside Russia to be hard convincing, Moscow's response to Kiev's strikes at Crimea or any other Russian region deep inside the country can be any, but it will be hard and convincing. Russian Security Council Deputy Chairman Dmitry Medvedev said in a written interview for Nadana Friedrichsen published on her Telegram channel. Our response can be any, he said answering a question. The president of Russia said it quite definitively. Medvedev explained that Russia sets no restrictions for itself and depending of the nature of threats can use all kinds of weapons, in accordance with our doctrinal documents including the basic principles of nuclear deterrence. I can assure you, the response will be swift, hard and convincing. The politician added, according to the Russian Nuclear Doctrine, Russia may use nuclear weapons if nuclear or other types of weapons of mass destruction are used against Russia or its allies. If it receives verified information about a start of ballistic missiles for attack on Russia or its allies, in case of enemies influence on facilities, vital for response nuclear action and in case of conventional aggression against Russia, if the very existence of the state is endangered. While Russia accepts the possible use of nuclear weapons as a legitimate battlefield tactic and its threshold for such use is far lower than for Western nuclear powers, its persistent nuclear threats should be recognized as primarily political posturing unrelated to any probable nuclear use. However, while all these factors demonstrate that Russia's attitude to nuclear use is significantly different from that of a NATO nuclear power, this attitude does not set preconditions for reckless, pointless or suicidal nuclear attacks in response to marginal threats.
