Regardless of the culture or back ground all radical groups become de-radicalized. The leaders and followers of these groups realize that the best way to progress or win people is through peace, constructive solutions and education.
Rather than dictate the leaders of all fringe groups decide that the best way is through peaceful discussion with opposing parties.
Leaders the world over decide that it is in their best interest to work for the betterment of mankind rather than for their own greed, benefit or for their own self aggrandizement.
War, bombings and all forms of violence are abandoned.
All terrorists groups listed on http://en.wikipedia.org/wiki/List_of_designated_terrorist_organizations abandon terror bombings etc as a way to get publicity or to try to get their own way. The movement towards peace, inter cooperation, and trying to learn from other people gains momentum and begins to run rampant through out the whole Earth.
