Hm, the German generals probably would not "blame" God, though maybe "providence"...or rather, misfortune. Were they true God-fearing men, they never would have condoned the SS or the Nazi Party or their atrocities...nor their own atrocities.
Anyway, there's always an argument for "What if?" That doesn't negate the reality that God does intervene in the events of man. Sure, the soldiers (either side, depending on your point of view) played their part, but when God acts....he acts.
So true is that principle that, when facing a vastly superior force in the Midianite and Amalekite armies, God had Gideon reduce the size of his army to just 300 men, so that, when God gave the enemy into their hands, the men of Israel would not be able to take credit for the resounding victory. They rightly gave God the glory and His name was in the minds of the soldiers as they won a battle at night....the enemy soldiers slaying each other out of mass confusion at the hands of the Lord!
The details of that event are recorded in Judges chapter 6 of the Bible. It's an example how God makes a habit of doing amazing things with little or no help. He often takes the weakest among us, and uses them to perform great miracles or to make them champions in his name. Another wonderful example is how he takes a helpless victim* and makes him a prince — a Prime Minister, in essence — second in power only to Pharaoh in all of Egypt. He takes all of us sinners and makes us saints, if only we accept his Lordship over our lives.
It is no big thing for the God of the universe, who takes an interest even in the lives of individual men, such as you and me, to cause a winter snap to turn the tide of war. Is it any wonder that the Russian army would even want to take credit for the weather? I would hope none of them really thought the victory was truly theirs...for it was the Lords!
Oh, how I love to sing a song of victory!
So here's the refrain from one of the songs my music group did in Church, yesterday...."Victory in Jesus"
O Victory in Jesus, my savior forever.
He sought me and he bought me, with his redeeming blood.
He loved me ere I knew him, and all my love is due him.
He plunged me to victory! ...beneath the cleansing flood.
*The events of Joseph, son of Jacob, and how he came to become second in command over all in Egypt, save for the Pharaoh, himself, are recorded in Genesis 37, 39-41. The events that led to that are then resolved in the following chapters, but those first few chapters tell of how God takes a young man, rejected by his brothers and sold into slavery, would rise to save many peoples, namely the Egyptians, but also his own family, despite their treachery, and also that of anyone who would come seeking food during one of the worst famines ever to hit that era.

It seemed like such a waste to destroy an entire battle station just to eliminate one man. But Charlie knew that it was the only way to ensure the absolute and total destruction of Quasi-duck, once and for all.
The saying, "beating them into submission until payday", is just golden...pun intended.
