While I empathise with Hadrian's take, he ended up in a middle ground that put us where we are today, with scattered Jews. He should've either kept Jerusalem so they always go back, or chase every last one of them and raze the city like Rome had done with Carthage. I have never had problems with Carthaginians subverting my nation.
Now, I'm not against Jews; I just support Jew control. With the proper regulations, we can farm them in a safe environment to slaughter in our festivals for years to come.
