The Islam religion is why we fight all these wars.
I suppose then we ought to recognize that the radicalization of Islam is our own creation. We can thank the administration of Jimmy Carter and those that followed for creating this nuisance as a part of their effort to insure that there was a steady flow of Mujahedin to fight the Russians in Afghanistan. The Russians were already aware of the vast mineral wealth to be had.
Then, too, we must address American foreign policy, nation building, and meddling in the affairs of other sovereign countries as well as the political, military and economic hegemony we have always sought to put in place as we position America's corporate structure to benefit atop the pools of spilt American blood.
Islam has been radical since its inception. Leave it to the self-loathing blame-America crowd to try and say an elitist theocracy that has been engaging in the same violent behavior for thousands of years were just a bunch of peaceful doves until America's foreign policy came along. What's next, 9-11 was an inside job and the moon landing was faked?
