This is stated in the decree on the foundations of state policy in the field of nuclear deterrence, which was signed by Russian President Vladimir Putin.

The decision to use nuclear weapons is made by the head of state.

Among the conditions for the transition to the use of such weapons is the receipt of reliable information about the launch of ballistic missiles attacking the territory of Russia or its allies.

One of the conditions is the enemy’s impact on the critical state and military facilities of Russia, the failure of which will lead to the disruption of the response of nuclear forces.

In addition, aggression against Russia using conventional weapons is called a condition when the very existence of the state is jeopardized.

On June 2, Putin approved the foundations of state policy on nuclear deterrence.

It follows from the document that nuclear deterrence is aimed at ensuring that the potential adversary understands the inevitability of retaliation in the event of aggression against Russia and its allies.
