I have disagreed with most everybody, so I might as well add you to the pile..
Having more Tigers, Sturmgewehrs, etc. wouldn’t have changed a thing - we had air supremacy and from Normandy on, more highly trained and reliable troops.
The Germans didn’t have a prayer from the moment they attacked the Soviets and declared war on the US.
The ME-262 was a dandy plane but it was armed for bomber interception. The four slow-firing 30mm cannons were poor armament against the more fleeting targets that fighters represent. The Brits had Glister Meteors operational and we had our first P-80s in England by May 1945. Either of those planes matched the 262 and had better fighter-to-fighter armament.
The V2s and V1s were useless terror weapons. A 1 ton payload thrown randomly at innocent bystanders. Served no purpose excepted make us angrier and less forgiving when we got done.
We won, they lost. They thoroughly deserved to lose too.
That’s Gloster, not “Glister”. One of these days, I’ll learn to proof better..
The Germans were doomed when they invaded Russia and declared war on the U.S. Our capacity to manufacture and innovate was just too great for the Axis. Which is why we could fight wars on two huge fronts and win. And if everything else failed, we had the atomic bomb.
