65 years to correct?
Consider the British Empire in 1914 and then again in 1971. It's more or less the same for all European nations. We lost our minds, a generation, many of our cities and all of our empires. 65 years is not going to correct that, it was a one-way street.
Do you have ANY understanding of the state of Europe's economy following WW2? We were heading for WW3 after the US pulled the mat on the debt repayments. Luckily Marshal understood this and hence the Marshal Plan prevented WW3 in Europe.
