>Anyway I don't believe in a ww3 happening like all the wars ~100 years ago.
ppl were saying there's no way there could be a conventional war today anymore – but 2020 the Karabakh War proved that wrong. We'll see.
>Before one of the big countries loses they'd probably rather press the nuclear nuke button and make everyone lose.
I'm actually wondering.
What if nukes are way overblown in popular imagination, and only an actual nuclear strike again will blow this delusion away? What happens then?
Consider the following: Hiroshima and Nagasaki were basically built of cardboard. Japs didn't have sturdy buildings then.
But – among the buildings that were not much impacted, were the few that were built of more than just cardboard: the churches. The Jesuits who were in the church at the time of bombing survived unscathed. Christians will claim this to be a "miracle", but everyone who knows some basic nuclear physics understands that a couple 10cm of rock will block most of radiation, so if the structure can survive the blast it will also shield everyone inside.
Dropping the bomb on a major European city would level the blast zone – but destruction and death would be much less widespread than it was on Japan.
