Individuals in an upstart county called America vs a 1400 year-old never exterminated jihad war machine with asymmetric warriors roaming freely over the entire planet who have made unprecedented advances in the last 15 years. Odds?
Remember that - in the end - Islam always loses. They overextend themselves. They burn themselves out. Internal strife prevents them from building anything of lasting importance.
What if ISIS had immediately declared themselves a real state, sent ambassadors to European states, laid off the public atrocities, and conducted themselves with at least a modicum of civility in their international relations? Everyone from McCain and Obama to Merkel and Hollande would have been lining up to recognize them, to give them financial aid, to name them "partners in the search for Middle East peace."
But Islam is incapable of that. Atrocities, they are expert at. Governance they can't handle. So ultimately, they will always run into some motivated leader - Martel, Sobieski, today (apparently) Putin, tomorrow maybe Trump or Cruz, and get their heads handed to them.
Considering the crybabies on our college campuses who would likely join the terrorists? Not good odds for us. They're Ayers and his band of Weathermen in training.
