Jeff Jacoby provided a comparison to the Third Reich. But as Islam is an ideology and militant organizations and governments are based on this ideology, then more logical would be to compare the situation to the Third Reich and the Nazism. It is hard to Islam to coexist with the modern culture. The statement, that if the land belonged to the Muslim it is forever Muslim land, is a source of tensions from Spain to the Israel, to the Armenia, to the India. The requirement to kill apostates contradicts to the freedom of religion and so on.
