Corrections:
The Baltic countries were Invaded by the Russians 1940, they should still be independent by 1939
Zyprus was under Britisch rule
Island belonged to Denmark before WW2, after the invasion of Denmark, Island was taken over by the Bristisch, then the US....
few more cities misplaced.
France: Reims, is actullay East of Paris, not so south of France, Cannes is a southern Coastal city (the Cannes you placed could be renamed in Mulhouse). Marseilles is more to the west, as is Lyon. Seine is not a city, can be renamed in Nancy, east of which should at least be Strasbourg
