Neither are you correctly identifying the root problem. The root of the problem is not radicalism; the root of the problem is islam itself. What the world is going through now is just the most recent iteration of an islamic resurgence. Eliminate all the radicals today, and in 50 or 75 years mankind will be right back where it is now, fighting for its life against the latest poisonous outgrowth of islam. This iteration was more or less kicked off by a muslim named Qutb who lived for a time during the '50's in Greeley, Colorado, and was incensed by the "immorality" he saw there. His subsequent writings spawned the muslim brotherhood.
Until mankind shows the willingness to eliminate islam, islam will continue to rear its ugly head and people will die as a result.
Of course it is... of course it is. Islam is no more a religion than communism. THat is obvious to just everyone in this country with a brain, but you can’t even get these people admit that there is even a more radical element.
I’m sorry to say this, but it will take something really big, to change thinking. I mean someone dynamiting the Hoover Dam, or the Statue of Liberty...etc.
