False.
Byzantium was only captured by turkics in 1453. That was less than 600 years ago.
Romans dominated the entire Middle East North Africa Balkans Anatolia London Paris from over 2000 years ago.
You can see to this day the vestiges of Roman influence. Turks abandoned Arabic alphabet and copied Roman alphabet because they thought their populace would remain analphabets otherwise.
You can see the entire Middle East in ruins and still their rulers are vassals of the West, with not a single bomb or nuclear chemical or biological weapons attack conducted anywhere in the West. Instead it's them who are getting shafted regularly.
That's been the standard for over 2000 years.
African slaves were a thing in rome over 2000 years ago.
China was never dominant beyond the Mongoloid sphere.
Greeks conquered all of Iran. They simply are not good at warfighting. Could any Iranian ever capture Rome? Arab? Turk? Mongol? East Asian? Afghan? Kurd?
No. Never.
They are not good at fighting wars.
What planet do you live on? Rome never dominated the middle east. It was always split and in dispute between Rome in the height of its power and Iran.
Also there is a huge difference between the eastern/western roman empre/ and the united Rome that fought Iran
Some of the most brutal beatings Rome sufferered were by Iran. From battle of carrhae where the advance guard of the Iranian army slaughtered the main roman army, captured all their eagles, andlsauhhtered crassus and his son , which threw Rome into a civil war between caesar and pompey
To this famous occasion :
Thats roman emperor valerian and future emperor philip the arab. The entire roman army was slaughtered/ captured to the last man by shapur.
Valerian was taken in chains and forced to kneel and used as a step for shapur to mount his horse on. This also caused severe instanility in rome.
We also slaughtered julian the apostate in a different war, surrounded his army, and instead of slaughtering them, sent in ambassadors to force huniliating terms in exchange for their lives
The roman heavy infantry never could fight the Iranian heavy cavalry. Iran learned its lesson from alexander, and most elite units were mounted heavy cavalry. Roman generals were terriffied of Iranian xavalry and usually resorted to trickery to try and defeat Iran.
