With a POD after 1900, make it so that a second World War occurs in the 1930s-1940s, with the USA and Britain on one side and Germany and Japan on the other. Germany must control (militarily and/or diplomatically) Europe from the Pyrenees deep into modern Russia at one point, but must still lose.
Bonus points if
-Nuclear weapons are used in the war, but not anytime after
-Italy is allied with Germany
-Russia is communist
-Poland is important in some way
- (just for fun) Winston Churchill (the war correspondent) is Prime Minister of Great Britain at some point during the war.
