Of course there is many historical facts. The only thing that can change is how we “interpret” (understand) them.

Look at the time of Reformation, especially in France where wars of religion occurred for more than 30 years ! Even before, between Rome and Constantinople, you had that schism dividing Christians !I don't even talk about the polemic regarding the relationship between Pope Pius XII and the Holocaust has long been controversial, with some scholars arguing that he kept silent during the Holocaust, while others have argued that he saved thousands if not tens or hundreds of thousands of Jews.Why Turkey, Egypt, Algeria and other Muslim countries are struggling against their clerics trying to promote a religious policy ruling every aspects of the society?  That's the reason for the decline of the Muslim world and the current danger awaiting these countries.

Don't expect any religion or religious people to be rational. By definition religion is irrational. Someone said, years ago, that religion was the opium of the people ("the opiate of the masses").  😛

I would like to be careful while stating that History as a social science is subjective !! When you look at the etymology of History, it comes from the Greek language, meaning investigation. That's what historians are doing, have a look at the history of History throughout time...  😛 G. M. Trevelyan reasserted the principle of history as an art as well as a scientific study.But historians are observers and participants, the works they produce are written from the perspective of their own time and sometimes with due concern for possible lessons for their own future.I remember when I was still a student at the university that our professors especially insisted about the respect of the historical method: source criticism, external and internal criticisms and so on.That's why I stated about subjectivism in History.  :-[

Scythians were Indo-European people who lived in a vast area covering present-day Ukraine, Russia and Central Asia who spread around 3000 BC. These Indo-Europeans were the first to tame horses and were part of the so-called Indo-European migrations.  In the late Antiquity, the notion of a Scythian ethnicity grew more vague, calling any people inhabiting the Pontic-Caspian steppe as "Scythians", regardless of their language.  Even during the Antiquity, Scythians seemed to be quite mysterious (see Strabo and Herodotus).

Remember the German battleship Bismarck which was to have attempted to intercept and destroy convoys in transit between North America and Great Britain.The fact is that Germany, especially the Third Reich, never had a sea supremacy.I agree that the major mistake of Hitler was his Operation Barbarossa when there was a pact between Stalin and Hitler(see invasion of Poland). A two-fronts war was unbearable for the Nazis.

A part of the answer can be found through the change, I should say the revolution, made by Kemal Atat?rk: admirer of the Age of Enlightenment, he sought to transform the former Ottoman Empire into a modern, democratic, and secular nation-state. The latter being the most crucial point, religion is by definition a brake for evolution therefore something to keep under control. A parallel with Western history can be made (Anglicanism, Reformation, French Revolution, separation of powers).
