Some countries "might be brought to ruin by the clash of jihad and crusade."
I thought that's what might have you disturbed. It's nothing new, though, Strother. Most of the great European nations that formed Western Civilization for the 500 years leading up to the American Revolution can trace their origins, at least in part, to the old nations and empires being rendered to dust by the clash of jihad and crusade. Now, I can agree that the thought of living under Sharia doesn't exactly fill me with glee, but I really don't think the United States is one of those countries to which Pipes was referring. In fact, falling to jihad is about one of the last downside outcomes for this country that I can imagine. The places to which he was referring are going to be in Africa and South Asia, where there already exists an interface between Christendom and Islam.
The United States is far more likely to fall under its own weight, or crumble from within as the underpinnings of a moral society are continually eroded by the tiny minority who think as Tucker does that humanism is a reasonable substitute for spiritual morality. As long as the majority of people, who still believe in the fundamentals of the Christian Faith as they are delineated in scripture, refuse to confront the agit-prop and whispering that the social justice warriors are selling, those foundations will continue to wash away and we will decline and fall just as the Empires of Rome and Old Europe did before us, and for the very same reasons.
What I find particularly interesting are the continuing parallels to traditional interpretations of the events described in The Apocalypse. But then, we can't make any better guesses about what that means, can we?
