I said "last 50 years", which means since 1970. If you think that WW2 was still a meaningful factor in economic output in 1970, you are in a very small minority and are making some very unusual claims.
Korean truce was announced 13 years before 1970: that's the distance between 2020 and the last recession. Taiwan's northern territories were still being shelled. Vietnam war was still ongoing. China just stopped the campaign of exterminating sparrows and intelligentsia.
