Is it possible to imagine a scenario where the West stays Lilly white until today? And White Australia and the immigration act of 1924 essentially goes on and on forever? Like if the Nazis implode after 1933 after the Reichswehr declares a coup, so no WW2 (at best a minor German Polish border war that results in Poland losing its Baltic access), and white racism and sense of moral superiority, and low grade 1930s antisemitism and eugenics basically go on and on. Basically in this scenario, the Great European powers may still lose their colonies, but instead of the British or French deciding on mass immigration, they decide to wall themselves of from their former colonies after losing India or Vietnam.
