Except its not going to be "americans shooting each other". It will be the immigrant population supported by Gov (secretly or openly) against everyone else, who by that time have been herded into regions mostly inland landlocked and trapped. At some point it will be all out WAR including air support by Gov.

This is why the KoC Latins have been staging the massacres to disarm the Americans, for a coming war with immigrant Latins. The Muslims will be part of it allied with the Latins. It may even begin as a fake war between the Latins and Muslims, but guess who will suffer the greatest losses? American non-Latins.

If the Lord were to allow such a thing, but I dont think so. I have faith He would come and stop the entire world before then.
