I believe that totalitarian regime called Nazi Germany had ( with the exception of ABomb) the most advanced technology. Ballistic Missiles, First Jet Fighters, Best Tanks, etc. etc. The problem was the political philosophy that dictated how and when to use them. Oh yes, I seem to recall that the other totalitarian regime, The Soviet Union, was the first to Orbit satellites and a Man, but as above the flaw was in how to utilize those advances without always having to fit into a Doctrine.
