Interesting to see this popular myth still being regurgitated when someone as perceptive as Bertrand Russell who lived through part of it admitted it was self-aggrandizing propaganda. In truth 80% of the British "Empire" were impoverished Indians. While back at home the Blue Books were churning out shocking reports of the misery and physical state of the British working class compared to their American and European peers. Read the archives from the early 20th century for a real eye-opener. And to top it all off, the "rule the waves" trope when Britain lost the Battle of the Chesapeake, aka the one naval battle that truly mattered in its history.
