Germany was defeated because we outproduced them 18:1 when Germany wanted the most sophisticated weapons that could not be mass produced. Today, the arrogance of the Neocons have transformed the United States into Germany of WWII. We spend millions in missiles to destroy a $30,000 drone. Iran is using a war of attrition against the US and Israel. I hate to point out that they still have 70%+ of their balistic missiles.
Then China can out produce the United States in a war the same as the US did to Hitler. We have become the arrogant power and assume we just win automatically because we have the most sophisticated weapons. But like Germany, we cannot mass produce them.
