So then perhaps a better poll would be what round do you switch to European front as the US? It will be important to add that yes we all know all games are different, this is asking for an average. For my latest game US turned to the Atlantic on turn 7. After chasing off the Japanese fleet, then capturing and building an IC in Korea.
And what was the situation in Europe after that?
Still to be decided, this game is not over yet. Germany has reached the German Soviet border and made sure to take and hold all german territories this past turn.(7) Italy has been bringing 3 turns of 4 trn loads to Syria, a large Italian army is present in Iraq/Persia/Npersia and Most of Germany’s navy is in the Caribbean protecting panama and putting a threat out on the US coast.
