While true, this is Nazi Germany we are talking about. These guys were a small country that bloodied the nose of Russia, swiftly occupied half of the Continent and beat us to computation and jet propelled aircraft in the midst of doing so. Imagine replaying that game of Age of Empires knowing not to research Gargantuan Tanks and putting all your marks into Messerschmidt. We'd have been fucked, we wouldn't have jet fighters until the 1950s, and without us no one would have had the homework to copy - or, our copy of the copy of the Berlin Patent Office, at least.
They were innovating at a staggering rate. A side project of Der Fuhrer ended up being the most popular vehicle of the 21st century, the Volkswagen Beetle. VW AG is still one of the top 5 players, and for a minute was the biggest automotive concern in the world.
The USA had to throw massive amounts of money and war materiel at fighting the wrong enemy - Russia wouldn't have even had electricity without General Electric going there and doing the dumbest fucking thing ever, 'hurr durr line go up, let's give vodkaniggers lightbulbs because profit.' In order to fight a war you need more than just pylons pumping out Zergs, you need money and raw material - if not finished goods, vehicles and weaponry for sale. See also the UK, the UK wasn't going to do shit to Germany without massive amounts of raw material and cubic yards of cold hard cash. Those frogs were whittling planes out of wood, ffs. And they did at least make stuff that was the equal of other modern powers, hard to argue with old Bentleys.
