Really, Germany?

[Wyrd of Gawd]

In the Bible the God character got really pissed if his minions showed the slightest mercy 
when he told them to kill everyone and everything.  You can bet if the God character had told Americans to engage in a genocide they would have killed everyone without a second thought or the slightest hesitation.  One of our favorite activities during WWII was burning people alive.  The Nazis were wimps, which is why they lost the war.

They lost the war because they picked a fight with everyone at once. They had rather weak allies in their own little group and decided to take on not only the Russians and Americans but also the British who could mobilise the resources of their empire and still had the most powerful navy in the world. After lightening war only got them so far they were stuck in a war of attrition that they couldn't possibly win.

The Nazis actually lost the war for maybe a thousand reasons.  The primary reason was that they were basically stupid.  They were done for as soon as they fired the first shot.
