Very simply, it is part of Islamic theology/ideology that the whole world become Islam. I'll never forget the banner that I saw unfurled in Afghanistan (on the TV screen) shortly after 9/11: "Afghanistan: the Greatest Conquerors of All". That says it all. One of the main "commandments" of Islam is to conquer. And then to convert the population. If a person resists, he/she is to be killed. Non-Moslems are never to be on the same level as Moslems. They are "dhimmi" - a class lower than Moslems. If this threat is not defeated, WE ARE IN TROUBLE.
