Russian President Vladimir Putin signed a decree approving Russia's updated nuclear doctrine, reported Xinhua, quoting the Kremlin on Tuesday.
The decree, published on the Kremlin website, states that aggression by any state in a military coalition or bloc against Russia or its allies is seen as aggression by the entire bloc as a whole and aggression from a non-nuclear state, with the involvement or support of a nuclear power, will be regarded as a joint attack on Russia.
According to the document, Russia views nuclear weapons "as a means of deterrence ... which is a last-resort and forced measure," and the country is taking "all necessary efforts" to reduce the nuclear threat and prevent the escalation of interstate tensions that could lead to military conflicts, including nuclear ones.
