The "Byzantines" were the Romans, and their Empire was the Roman Empire, the whole eastern half, with possesing in Africa and Italy when the arab conquests happened. Probably without Arabs, and Turks later as a consequence the Eastern Roman Empire could last to this day, even severely crippled, weaked and abused this lasted to 15th century. The only bigger problems for them is, I could see, in the Balkans, which they de facto lost even before the Arabs came, but later under the Macedonian Dynasty they were able to reconquer it and hold for two centuries. For Sassanians, I don't know, probably to the time when some steppe barbarians managed to do "full Chingis Khan" rampage.How much longer would the byzantines & sassanids have lasted without the arab conquests? could the byzantines have rebuilt the roman empire? Is it likely the turks & mongols would still take them down?
what would have happened after a sassanid collapse?Byzantine, which was Roman Empire to end, could survive this day. It probably could survive with any POD before fourth crusade.
Sassanids probably wouldn't survive much longer. Dynasties rarely survive several centuries and Persian ones were often pretty short-lived.
what would have happened after a sassanid collapse?
Seems to me balkanisation of persia would have left the romans in a pretty good position if no muslim/arab invasion.
The Christians of Iraq would either try to form a new state and get conquered by the Sassanid successor, or join Rome and be the catalyst for further wars between Rome and Persiawhat would have happened after a sassanid collapse?
No. Wrong type of Christian.The Christians of Iraq would either try to form a new state and get conquered by the Sassanid successor, or join Rome and be the catalyst for further wars between Rome and Persia

Said Christians disagree with you on this.

Well, we can just look for an inspiration into the OTL. But without lost of the Eastern Provinces, and without a total turkish/arabian threats the Eastern Roman Empire should be stronger.The Byzantines can remain in power but I am interested in seeing how it will face the issues of the Balkans and the rise of other Christan European powers. Egypt is easier than Balkans to keep due to historical low number of internal problems unlike the Balkans with first Germanic invasions then facing the hungrains Russians and Austrians.
