That's not the most pleasant blueprint to follow...
Those wars scared everybody who'd grown up in the affected territories off religious absolutism for a very long time -- at least, off religious absolutism by the standards of the time: things were still grim by modern standards -- and created an environment in which philosophers could develop the ideas and concepts of the enlightenment without being burned at the stake for heresy.
The Arab world looks to be on the skids heading towards its own equivalent of the Thirty Years War right now. I just hope the eventual outcome is positive, and that they get to it faster and with less bloodshed.
Around when we were doing the 30 year war et al in Western Europe, the East Europeans of the area were writing edicts about religious tolerance. (Yes yes, a deplorable lack of fashion sense.)
That example sadly seems unlikely right now. But since soon all minority groups are thrown out of the Middle East, there won't be anyone left to hate (except for those that move to Western Europe).
When will the West do that ?
(assuming you live in the Western world.)
many of the dictators are either dead or crippled, and the world is awash in more terrorism than ever before.
It was surprising.
From what I've read, people living for a long time in dictatorships are quite intolerant and hateful. (There were quite a bit of intolerance in East Germany after 1989, too. And examples from Eastern Europe are well known.)
If/when the Arab world get rid of the dictators controlling the media and education gets better, they should become more "normal".
Or maybe I am too liberal in assuming every culture will walk the same path as us. I doubt it. Until someone comes up with something that works better, liberal [edit: and ~ capitalist] democracy is the least bad alternative.
