No. Not at all. For me, allowing something needs the freedom to decide. None of the soldiers had the freedom. If Rommel had refused orders again (and he did once by refusing to shoot captured enemy soldiers), he and his family would have been sent to the death camps, too. The same applies to the other Wehrmacht soldiers, too. Several hundreds had the guts to take the risk, and the outcome was widely seen after July 20 1944. It didn´t work, because Hitler replaced all opponents with loyal Nazis.
Sure they had the freedom to decide. They chose to submit.
