Dont understand why you get downvoted, as I assume you mean that the generals wrwe not strategical and tactical terrible. Think most historians will agree that Hitlers direct involvement in the war was a growing issue in conducting the war. Also Hitler stayed in power by making sure that the levels below him were at each others throats and not able to challenge him directly. Nazi Germany was not technically on a war economy until Speer took over, and the amount of corruption was immens.
