I'm not sure if the numbers support your conclusions. First off -- your comment about the Kaiser and Hitler is out of place since they took place after the end of WWI. In 1913 nobody could even have conceived of the impact that Hitler (and Stalin, Tojo, etc) would have on the world. You claim that Imperial Germany was expansionist -- compared to what? The only valid comparison is to Imperial Germany's contemporaries -- Great Britain, France and even "little" Belgium -- all had vast colonial empires. Germany came very lately to the colonial game and only managed to acquire 4 colonies in Africa starting in 1884, and a few more small territories in Asia.But even in WWI Germany and Austria were certainly very different than the Allies, they were correctly labeled as autocratic regimes run by a pre-modern aristocratic elite. They certainly weren't as extreme as the fascists later were but they pretty much thought exactly the same way as the fascists did. For example the Kaiser was largely supportive of Hitler and vice versa. Nazi Germany was also relatively mild prior to WWII compared to Soviet Russia.
Imperial Germany had an expansionist colonial program, I understand this is downplayed on the grounds that other countries were doing the same thing. Yet Nazi Germany's expansionist program has always been treated as proof of a desire for world conquest despite there being absolutely no evidence. Again, why the double standard?
If you compare the militaries of the 5 major combatants in 1914 as they stood in 1913, the picture is also not a clear cut as many would have you believe. Neither Germany's Army nor Navy is the largest of the major countries that would go to war in 1914. That honor rested with Russia and Great Britain respectively. The total of man under arms (combined Army, Navy and wartime reserves) as a percentage of the total population was also less than both France, Russia and Austria-Hungary in 1913. In hindsight it's common to dismiss Russia's military might as being a shadow of what the numbers suggest, but in 1913 the future weaknesses were not yet known. But even if you took Russia's army out of the numbers, and Great Britain's navy likewise out of the numbers, you still have the Entente's military power being greater than the combined Germany and Austria-Hungary.
So while the Allied propaganda portrayed Germany as the bulked up military dominated bully in 1914, the numbers don't actually support that view.
