It's so surprising that nobody ever talks about the active nuclear policies the countries have. For example Russia states the following:

> With regard to nuclear weapons specifically, Russia reserves the right to use nuclear weapons: > - in response to the use of nuclear and other types of weapons of mass destruction against it or its allies, and also > - in case of aggression against Russia with the use of conventional weapons when the very existence of the state is threatened.

As long as NATO doesn't nuke something first or the very existence of Russia is not threatened, they should not use nukes.

From this part on I am speculating only, but I believe if Putin would press the red button the officers would have the right to refuse to execute the order.
