You know when I visit arab neighborhoods I see everything called jerusalem this and jerusalem that, nothing named after what they should be happy to have such as mecca... Muslims as a rule are a covetous people who don't realize they are far inferior to those whose property they seek to commandeer in religion and morals as well as technology and military might. Only with the aid of natural disaster and chaos do they succeed in battle. From the start the west and persian empire were in decay so they succeeded as an organized force in the midst of dead empires. They will only succeed again should there be a serious natural disaster or economic failure and in that case it would be pyrrhic, to the detriment of the whole world because it will stifle progress in return to civilization...
