“The Roman destruction of Jerusalem in the Roman Wars/Jewish Revolt was at least as significant to the transformation of the Israelite nation as the Exodus was.”
The war was probably carried out by Auxiliaries, locals who had been recruited and then led by Roman officers. It’s my understanding that the destruction of the Temple in particular was done against the orders of Titus.
I doubt that Titus was against the act itself.
