As a Briton myself, I felt rather depressed after I learned of the decline of the United Kingdom and its transition towards a German satellite after the Race Invasion of Tosev 3, in Turtledove's 'Worldwar' and 'Colonisation' series.
Within the scenario of this extraterrestrial invasion mid-WWII: how can Britain maintain more of its Empire post-war; which parts of the Empire would likely remain; how can it retain a status at least equal to that of the Empire of Japan; how can it maintain a foreign and domestic policy distinct from that of other powers; and how would a surviving British Empire interact with the Race and the other surviving human 'not-empires'?
Bonus points if there is a realistic way of the UK becoming a space-faring power.
