I'm sorry, but Hitler was NOT a talented statesman. In domestic affairs he was a demagogue, in foreign affairs he was a thug. He gained the support of the German people by appealing to the worst side of them, and was able to do so because the country was suffering from an economic depression and the humiliating surrender terms of Versailles. He stayed in power by employing state-sponsored terror against his own people. His only foreign policy "achievement" that didn't involve the use or threat of overwhelming force was the Molotov-Ribbentrop pact. That was just a device to buy time before his invasion of Russia, and since its ultimate outcome was the defeat of Germany by Russia, I'd consider that a failure as well.
Compare Hitler to Roosevelt, who rallied his demoralized country out of the Depression without resorting to murderous secret police, or Churchill, who forged alliances through diplomacy rather than forcing them at gunpoint, and you'll find that Hitler fails pretty much every "great statesman" test you care to name.
That being said, if you want to play Hitler as a civilization leader, hey, it's still a free country. I admit to getting a perverse thrill out of playing the Axis from time to time.
But as far as German leaders are concerned, I'm a big fan of Bismarck. Bismarck literally created the German Empire, drafting the constitution that united the German states. He fought wars in the manner of Clausewitz, using them as a continuation of diplomacy. Bismarck's wars were short, had clearly defined goals, and ended when those goals were achieved. And in the decades following the 1870 unification, Bismarck devoted his energies to preventing a war, assuring that Germany was never isolated on the European power stage. He also, despite his personal hunger for power, was responsive to the wishes of the German people, turning Germany into the most socially progressive nation in the world for that time.
The Germans should feel just as much pride over Bismarck as they feel shame over Hitler.
