Notice the americans played differently with the Germans and japanese afterwards and look at em now quite the success story
Not really. Germany and Japan were decimated to an unprecedented level by the end of ww2. Those countries turned around when the population gave up their idiological faith in their dictators and associated pseudo-religious political movements. They threw away their copies of Mein Kampf and realised that the emperor was just a mortal dork like everyone else. So too, only when Muslims put aside their instruction manuals on subjugation and murder will there be hope.
