Suez as a turning point rather than an instant collapse

Did the Suez Crisis mark the end of Britain as a major global power?

Contemporaries did not treat Suez as an instantaneous ending, but it exposed US predominance, split Britain from France, removed Anthony Eden, and accelerated a wider contraction.

British global power did not end at one instant in the Suez Crisis. At the time, the event was not universally understood in those final terms. It did demonstrate the United States asserting itself as the pre-eminent Western power and revealed a serious split between Britain and France. The domestic political casualty was Anthony Eden rather than Harold Macmillan. Suez still mattered because it set off and accelerated reactions that combined with later decisions in the 1960s. It is best read as a sharp turning point within a longer process.
