It's not even comparable with the impact of a single nuke let alone nuclear war.
On another note, while Japan has recovered very well — thrived, even — after the impact of two nuclear weapons, the Soviet Union never did fully recover from its Afghanistan debacle, which was part of the background for its eventual collapse. Don't underestimate the undesirability of nuclear attacks or disastrous wars that can neither be won nor gained from.
The bomb dropped on hiroshima was more than an magnitude smaller than a standard bomb these days.
> was 884 million yen, about 1.2 trillion 2021 US dollars, by my calculations.
~884 million yen at the time but that's a relatively meaningless number. A better measure would be 2% of economic wealth of Japan at the time which is where I assume you came up with the second number... for a 20kt fission type bomb dropped in a city of 350,000. A modern bomb 10x the size dropped on a modern city 10x the size is going to be measured in the 10s of trillions in costs - instantly for a single bomb, not part of a 20 year funding campaign that ends up recirculating a lot of money in the military industrial complex.

2 weapons totaling the 10th of a normal weapon at a time no other country had a nuclear weapon to retaliate with.

Sure, plenty of things compounded have led to the downfall of countries over the last few thousand years. I can't however think of any reason or even set of reasons that would be comparable to millions of citizens dying overnight due to instantaneous deletion of a major population center... x100.
