We're more realistic. We hope it will never happen. But we fear it might. Strategic nuclear bombardment is something that should be feared, not pooh-poohed.

And how exactly would that change the military strategy of a non-nuclear armed European strategy (save for NBC protection in armored vehicles I suppose...) or even individual people?

For me it just makes zero sense to lose much sleep about it, except for voting I can't do nothing about it
