Not even worth worrying about bear. You’re always carrying on about nukes. The US loses wars all the time, and doesn’t spit the dummy and use nukes. Russia uses nukes, they’ll get nukes back. You can’t sit awake all night every night worrying that Russia could use nukes. They could have launched a pre-emptive strike last night, they could launch one at 3 am tomorrow morning. Worrying about it won’t achieve anything.
