Do you think it would have been possible for the British Empire to survive if WWI and WWII had never occurred?

If the British Empire had survived to the present day, it would either have had to liberalize to become a meaningful worldwide transnational polity for everyone who lived inside it, or it would be a grim and likely very racist empire where whites would be privileged over non-whites. There would be no middle ground.

an expansion is one of two basic business cycle phases; the other is contraction. the transition from expansion to contraction is a peak, and the changeover from contraction to expansion is a trough.
