You are making an assumption that the Arab-speaking world can govern itself in a pluralistic, progressive, secular (giggle, giggle) and mature way. I make so such assumption. Until they do that whole Reformation-Counter Reformation-Renaissance-Age of Enlightenment-Peace of Westphalia-Industrial Revolution-Spread of Socialism-World War-post history "thing", they will largely remain frozen in time as people who want to restore a time and place that a Mongol invasion took from them in 1258.
You make so many assumptions about history it's difficult to know how to begin responding to your post.
We'll start with the obvious: you assume history progresses in a line, which is not true. You assume history is characterized by a single, universal path of development, which is not true. You assume that the Western model is normative, which is not true.
Next, you assume there is any legitimacy whatsoever to this "yearning for the past" supposedly exhibited by--who, exactly? All Muslims? Who is the "they" you mention in the last sentence here?
As you should probably know, the values of any of the real caliphates were drastically at odds with the values currently espoused by Daesh. The caliphates were tolerant (much more tolerant than contemporary Christian states--for example homosexuals were a frequent fixture in the courts of the Caliphs), multiethnic, and progressive. Indeed, the Rashidun Caliphate came closer to espousing those nice values in your post than any Western government for at least another thousand years.
As for a more modern example, we need make no such assumption. In the years after World War II, the Middle East was perfectly on its way towards governing in the manner you describe until the West toppled basically all of the nascent democracies in the Middle East and replaced them with various dictatorships.
Of course, one might wonder why you apparently believe it to be an "assumption" that humans can govern themselves in a reasonable way. It's almost as if you are prejudiced against Muslims (or is it Arabs?).
