When Hitler had Rommel killed (by choice of suicide or being shot), the war was pretty much lost for Germany. True, his death was due to Hilter’s insane paranoia.
Rommel’s chance could’ve come at D-Day. but he was back home, believing there was no way Ike would attack with the weather conditions the way they were.
In fact, if you want to credit God, He set up a LOT of things for the Allies to win the day....not the least of which was the Nazi’s utter arrogance that they could withstand and repel a major invasion.
After Stalingrad I’ve often thought that German Army wasn’t necessarily fighting to lose but it certainly stopped fighting to win. I think they were just trying to satisfy honor and collectively felt they might, at the outside try to bring the war to a stalemate or, in an oft expressed delusion by some German generals, including the SS, somehow convince England and America that their mutual enemy was The Soviets and together they’d all join together to defeat Russia.
