Tell that to those unfortunates in the countries it already dominates - about 1/4 of the globe, all countries which were once non-Muslim.
When Islam shows up with the sword, it is not just to conquer, but convert. Those do don't go along with the program either get eliminated or broken quickly and relegated to completely powerless, second-class status forever.
If Islam isn't isn't totally beaten in a country early enough, it quickly becomes "too late". You don't get a "second chance" with this deadly cult. It took centuries to drive the Moors out of Spain and that had to be done by outsiders, not the oppressed population. The resident population doesn't have a chance of doing it.
That's one reason Muslims are so furious over our invasion of Iraq. They look upon us as Infidel invaders who are trying to get rid of Islam, not just Saddam, whom they would happily put up with because he is a fellow Muslim. To Muslims, the House Of Islam and it's victory in the world is much more important than any little thing like "human rights", which in any case are not recognized in Islam.
