To me this is simple.

When a non military person decides what happens and when. It screws that whole system.

He should never have been allowed to order and design battles.

that being said: It would have been very hard foor the Generals and ranking officers to withold their support. It is well known that some did and that they either retired on their own or went missing. Hitler simply replaced those officers with idiots dedicated to him.

After a battle or line of defense is planed and setup. the civilian powers should have not had a single word. It should have been up to the general in charge on who and what get's deployed or when the reserve is used.
