Up to Barbarossa, I would say Hitler was far more rational*/strategic than the Kaiserreich. It seems like WW1 Germany had no contingency plan for the British ultimatum on Belgium and proceeded to go to war as if the British didn't matter.Terry Duncan wrote:Other than having no idea what to do about a hostile Britain, German policy in WWI was based on far more reliable intelligence and ideas on what was possible rather than the wishful thinking that dominated WWII.
By contrast, Hitler had great success in using strategy/diplomacy to enable single-front wars until he mis-gauged the SU. Hitler and his regime were adequately prepared for a long war against France in 1940...
*rational in a sense completely independent of ends. Hitler's ends were monstrous but his means of achieving them were fairly rationale until later '41.
