Germany and Japan have tolerant and compatible cultures, and &quot;world opinion&quot; was controlled by the Allies. I don&#x27;t think it&#x27;s possible to shape &quot;world opinion&quot; anymore. The Koran doesn&#x27;t permit any kind of integration and tolerance. Western &quot;nation building&quot; (rebuilding) is perceived as an attack on that religion. My own libertarian bent tells me that it&#x27;s at least an unjust attack on their way of life, how alien that might be to Westerners.
