The guy has a point with the Cyrus bit. Cyrus gets very good press in the Bible. He is even called the annointed of the Lord. The messiah.
Isaiah 45:1
Cyrus motivation was to expand the Achaemenid Empire. It was all about power and conquest. Cyrus was a thug. In empire building, first you conquer, then you pacify. Cyrus, and any emperor for that matter, cannot afford unrest in already conquered lands while still expanding the empire. Cyrus could have cared less about the religion of anyone in Babylon, other than from the point that religious appeasement pacifies the conquered.
However, what this history is not relevant. The current problems between Muslims and Jews, and Christians for that matter, go back to the time of Muhammad. The problems will persist as long as there is Islam. In Islam, deception (changing history) is encouraged. The Bible only provides a brief glimpse into history. History needs to be looked at in its totality.
