From my limited information, I gather you are mostly correct. Stiull, I do know that because of the (second) Jewish uprising, Trajan had to abandon his conquest of Iraq. The Romans never had much success in that area, as you know, it remained a frontier province. Finally, in the 7th Century, after the Romans and the Persians had beat each other to a pulp, the Arabs rode into to take the whole shebang.
“From my limited information, I gather you are mostly correct.”
Some of that is personal opinion.
“The Romans never had much success in that area, as you know, it remained a frontier province.”
I guess so. The Romans were mainly an infantry force although they did use auxiliary cavalry effectively at times.

Some things never change. The Muzzies are always there to exploit other people’s problems for their own advantage.
