The new doctrine outlines that Russia will consider using nuclear weapons against a non-nuclear state if they are supported by nuclear powers.

"Aggression by a non-nuclear state with the participation of a nuclear state is considered as a joint attack," Kremlin spokesman Dmitry Peskov told reporters, on Tuesday, a clear reference to Ukraine and its Western backers.
