We always talk like the world is united against the "islamofascists" and the states that support them, mostly in the middle east.
But what if most of the rest of the world is quite OK with islamofascism, and would rather see them win than us? What if we are not United against a common enemy? What if a majority of the world doesn't think islamofascism is an "enemy"?
That would explain a lot of what we've seen in the last 5 years. And it would portend a much darker, and more dangerous, future than we could possibly imagine.
There is nothing in history that requires that we march from less to more advanced. If anything, there is considerable backlash against the technologically advanced but numerically inferior. And that would be us.
Decaying civilizations of Europe may simply not care anymore about their own grand history and place in the world. They may think peace with the islamists is as good a fate as having to live in our shadow.
