Good points,, and also many actions throughout the War contributed almost nothing to the war except to assure the continuation of British and French colonies after the war. Countless died to make sure the colonial possessions remained in the fold.
Most of the operations in the Mediterranean were designed to protect British possessions in the middle east. Same for most of the actions in SE Asia.
American airmen in India observed that the English seemed more interested in maintaining the colonial order there, than in taking actions that might free india, even if it would help the war effort.
Much of late WWII was actually the battle to re-establish the pre-war colonies in Indochina, China, the middle east, and Africa.
Europe created decades more misery and millions more dead AFTER WWII because they wanted to continue their dictatorships around the world.
Well, they lost their empires, and Africa lost what little bit of civilization it had absorbed. Or... wait, maybe the brutality of the Africans was learnt at the hands of their masters the british, french, and belgians. And dutch.
