As I understand it, Britain went to war because their Polish ally was being occupied by a brutal foreign power. They continued to be occupied by a brutal foreign power until 1991.
They fought the Hun on the ground everywhere except for Poland, Yugoslavia the Russian front, and even there they offered to send divisions but Stalin refused unless they were under Soviet command.
Admiral Raeder's Mediterranean Strategy for the win.
Would have covered the southern flanks, secured oil, extended Brit supply lines by thousands of miles, and most importantly scared the shit out of the Russians because they would be so vulnerable (the only option in my opinion that would an inevitable Soviet attack, besides a sucessful Barbarossa (pipedream)).
Britain I think would have caved at this point, as their only option to continue their Empire would be to squeeze the shit out of the Indians.
Yes of course, why wouldn't you come to the shittiest in time point culture wise? The idea of a song these days is to do a cover with some shitty electronica.
It would be the equivalent of vacationing in Toronto.
