In 2021 Russian population 145 million, US population 331 million.
Last year Russia lost one million people (mostly due to covid-19). They will lose another million people this year (due to young Russians fleeing the country). So let's see. 110 million people by 2050? Maybe 2040?
A sizeable chunk of our population is not American and likely will never be American. Does Russia have the same open borders that America has? Even our f'n illegals get counted. That is at minimum 50-60 million right there.
