The world was more stable 1990-2020 than it was 1950-1980, yes. I don't think it's a good bet to assume that stability will continue. The pandemic will peter out, sure. But the US is shifting toward isolationism, China is heading for a population crash, Japan is rearming, and Europe is rethinking its strategic position in light of all that. That doesn't necessarily add up to increased conflict, but it does point to a lot of uncertainty.
