It all comes down to oil, the west discovers an alternative fuel and these "people" revert back to their true natures as date peddling nomads fighting with each other over watering holes. The only real problem would be getting western countries to shore up immigration policies because you know damn well that these kafir will be trying to escape their shithole countries to further infest ours.
We don't need any alternatives because human caused global warming/cooling/climate change is a lie and there are more than enough fossil fuel in our own country for us to be completely energy independent for a long long time.
