Political skill did not make Hitler a sound wartime strategist

Was Hitler's wartime failure simply the result of jumping from lance corporal to supreme commander without intermediate military experience?

A civilian leader should supply political-strategic judgement, and Hitler's success in Weimar politics coexisted with grave failures in the larger political calculations of war.

Military rank alone does not explain Hitler's decisions. A civilian head of government is expected to provide political strategy and to use professional officers for military expertise. Hitler's rise through the Weimar political system demonstrates tactical political ability within that setting. His wartime political calculations nevertheless failed on a far larger scale. His published writing also made his ideology and ambitions available for contemporaries to examine.
