Um, yes.

You honestly think Britain vacated its position as world superpower because of 1776-83?. You think winning that war made America a world power or THE world power?.

If you do, think again.

Britain’s Empire would expand from 1783 to 1939. After the war in America, British power would never be greater than it would be in the next century and beyond. The British Empire was the greatest power on earth until the Second World War.

To be blunt, overall losing America was just a blip.

Britain was THE superpower right up until the late 1800s, then it was challenged by the US, Germany, Russia to some extent

It was only knocked off top position by the US as a result of WWI (though this would have probably happened in any case over time as the UK stagnated from the Edwardian age)
