The Russian Ministry of Foreign affairs issued a statement saying Russia could “hypothetically” use nuclear weapons only defensively or if the very existence of the state is threatened:
Russia is strictly and consistently governed by the postulate that nuclear war is impermissible, there can be no winner in it, and it must never be unleashed. Russian doctrine in this area is extremely clearly defined, it is purely defensive in orientation and does not permit broad interpretation. A reaction by Russia with the use of nuclear weapons is hypothetically allowed only in response to aggression carried out with WMDs, or with conventional weapons if the very existence of the state is under threat.
The ministry said that its first priority is the prevention of any military conflict between nuclear powers. It called on other countries which possess nuclear weapons to “demonstrate in practice their willingness to resolve this priority problem, and to abandon dangerous attempts to infringe upon each other’s vital interests, which balance on the brink of direct armed conflict.”
