The war on christianity has been won, a millenium ago. The Romans won. The attempts to protest were also led by gatekeepers. How do I know? Usury exists and christian teaching on it is ignored!
Islam is therefore to be destroyed by reshaping. Demonize them as those who burned Rome. Sound familiar to 9/11 and 7/7 and Bali?
After that find useful idiots who will redraft the Koran, Qura'an, into an equivalent of the council of Nicea result. Spread the book and destroy those who know the original book, allowing that this will take generations. Ensure that women can be exploited to the full and that children can be taken care of by third parties who must "educate" them. In the meantime, buy all the oil and other resources that we can, to leave them impoverished.
Mohomed was a warrior and he will accept defeat. Ullah will still take souls damaged by borrowing too much. Religious engineering? Why not?
