I hear this arguement a lot from revisionists ,Nazi/Fascist apologists and Far right revisionists. "If only British did not foolishly declared war to illustrious Third Reich and let Hitler alone then British Empire would be intact. They could even wipe out Communism together by joing Hitler's Crusade to Soviet Union and a well deserved place in New Order" What is the source of this what if scenerio because aside from declaring Martial Law across Indian subcontinent , arrest members of Indian National Congress and shooting Indians at will in thousands as Hitler recommended to Lord Halifax in 1937 I can not see how Britain could still rule British Raj in India after 1940'ies with Gandhi's independence movement gaining momentum vastly with passive resistance themes (which could be converted to violent resistance easily by others like Chandra Bose and last time I checked there were a lott more Indians than British in subcontinent) , passage of India Bill from House of Commons in 1936 , gathering of Indian National Congress in 1922 and slowly shifting loyalty in ranks of British Indian Army. Same with Ireland where Irish Republic was officially proclaimed in 1923. Most of other overseas colonies already became Dominions in Commonwealth like South Africa , Canada , Australia and New Zealand with local elected goverments acquiring greater autonomy in their affairs. Or similar in overseas colonies and territories from Caribbean , Jamaica , Bahamas , West Indies where cost of keeping and maintaining these territories becoming far higher than the profits they generated and becoming an economic burden for UK which saw its finance and economy seriously damaged in Great War in 1914-1918 and Great Depression after 1929. British Empire was already cracking up during 1920'ies and 1930'ies , how letting Nazi Germany loose in Europe would benefit in keeping British colonies and dominions and benefit British economy ?
