Then came the day Rome burnt the Judean temple to the ground in 70 AD and kicked the most rowdy Judeans out of their land. These Judeans were pretty much known all throughout the empire as rebel rousers, so it was hard for them to find places where they could settle down and get back to money-changing.
Carthage obviously had a long resentment of Rome, so, seeing as how an eye for an eye and a tooth for a tooth, the enemy of my enemy is my friend, it would make sense for them to camp it out there.
And then…

After they had been kicked out of every slightly Roman city, mainly 2, Carthage and Alexandria, this was when work on the Jerusalem Talmud stopped and the Babylonian Talmud began.
These Rabbis and money-changers were no longer Hebrews or even Judeans, they were now Kikes and Shekelbergs.
Also at this point probably a decent portion of the Judeans that remained in Palestine had converted over to Christianity, and the rest were probably mostly following the Tanakh as Samaritans had already been known for only following the first few books. (also the Babylonian Jews probably had a grudge against anything greco-roman because of that one small amount of time Zeus was in their temple, oy gevalt)

All of our problems come from the reds and the oranges who fell for the reds (oh and the people who moved from orange to red turf and am became reds).
