In the world where RF is stupid enough to invade the nuclear country.
I'm from Ukraine.
To be fair, the only one even considering using nuclear weapons seems to be you, here on HN. No military or political planners are considering it because nobody wants to see Europe devastated in a nuclear war, and everyone understands this, which is why -- if there is war, hopefully not! -- it won't be nuclear.
If you think about it, YOU, an Ukrainian, don't really want Ukraine to attack Russia with nukes. Why? Because then you'd be dead, plain and simple.
