Exactly. I view the betrayal of Romanos IV by the Court immediately after Mazinkert as a likely cause of many of the subsequent downfalls of the Roman Empire. Mazinkert need not have been a disaster, because it was only after several years that the Turks started settling in Anatolia. The Evil One was undoubtedly at work in having the new Roman Emperor invite in the crusaders who promptly misdirected their energies from destroying the Turkish occupation to fighting and slaughtering their fellow Christians in Antioch and Jerusalem.
The bitter and stupid quarrel between the two Romes is also a probable cause for the subsequent judgement and puishment of both - the West by constant wars, the Babylonian Captivity and Great Schism and Reformation, the East by the destruction of all Roman civilization by the Turk. West Rome was given tremendous power and showed to all how it would dreadfully misuse it. East Rome was deprived of all power and allowed to sink ito oblivion.
It is hard to imagine that God will bless either of two brothers who insist upon quarrelling and haughty arrogance towards each other.
