Exactly. I’m scratching my head over a few things on this thread. One of them is that a lot of folks seem oblivious to the fact that Western civilization flourished after Jerusalem was sacked by the Romans and the Temple was destroyed.
Western Civilization flourished before, during and after the sacking of the Temple in Jerusalem. Rome was early in her transformation from the Republic to the Imperial system, right. So Rome had 500 years of greatness behind her, and many hundreds of years of expansion ahead of her, including the founding of Constantinople by Emperor Constantine in 330 AD.
From the point of view of Roman history the events in Jerusalem in AD 70 don't seem to be a particular fulcrum.
So we are oblivious because it's not really that important an event.
