Then the title should be Australian, British, Canadian, New Zealand, Polish and US Air Forces. A bit lenghty.
Concerning politics, status of Poland was different. Poland never ceased fire and legal government evacuated. Czechoslovakia as a recognised country ceased to exist in 1939 and the legal governments were at Protectorate and in Slovakia. Legal French government was at Vichy, hence all the fuss with Darlan back in 1942.
I cannot tell anything about status of Belgium, Netherlands or Norway.
