The Germans tried to invade the Russians in winter. Just like the French.
Oh and Riddler pussied out with poison, instead of something manly like going down shooting everyone.
How WWII should have ended:
Riddler - "Here I sit, with mein gun, mein wife, und in mein kampfy chair. Come at me, allied bros."
<Insert 15 second gun fire>
Newspaper - "Riddler DEAD!"
<For the following 67 years, there are no conspiracies about him still being alive>
BRILLIANT! Cut, print, sell.
