America came out unscathed and prosperous from WWII because it did nothing while the world destroyed itself and waited until the end when Russia had already done most of the hard work. Because of this American industry still existed and it sold to the world.
That is quite a misrepresentation of history. Have you ever seen the American cemeteries from WWII in France or Italy? Then you would know that for doing "nothing" quite a lot of Americans have died to liberate Europe. And the part they liberated actually stayed free as opposed to the dictatorships installed by the Soviets.
