He has plenty more ways to escalate before nukes. Take out under sea communications for europe, “accidental/ it wasn’t us” strikes on nuclear plants in Ukraine, take out the new gas pipe coming from Norway, “accidentally” ram satellites in orbit with Russian ones… the list goes on.
He can and will make life very nasty for europe/Ukraine before using actual nukes I reckon.
However tough it gets we can’t weaken though, he’ll only get even worse over the years ahead.
Oh and those countries that have taken in huge amounts of Russian men fleeing the draft now have “Russian speaking populations” that are being oppressed soon no doubt…
