And the major causative factor is the nation-building hegemonic US that has arm-wrestled its allies into wars of aggression against Iraq, Afghanistan, Syria, Libya and lord knows how many are in the planning stages. All the violence and bloodletting have served to do is create catastrophic destruction of infrastructure; re-ignite agent enmities; foment social unrest as a result of economic demolition leaving hundreds of thousands of people homeless, jobless, and rudderless, which makes them sitting ducks for recruitment by the likes of ISIS/ISIL promising jobs/food/health care/housing/education (all carrots that lead to the recruits becoming enslaved/indoctrinated/terrorized.
I close with the words from a Raygun speech in 1974: " Standing on the tiny deck of the Arabella in 1630 off the Massachusetts coast, John Winthrop said, "We will be as a city upon a hill. The eyes of all people are upon us, so that if we deal falsely with our God in this work we have undertaken and so cause Him to withdraw His present help from us, we shall be made a story and a byword throughout the world." Well, we have not dealt falsely with our God, even if He is temporarily suspended from the classroom.
