AHC/WI: The Hittites last three more centuries

With any POD necessary, make the Hittites last at least three more centuries.

What are the effects of this?

Also, is there any way they could conquer Egypt or Assyria?
 
This sort of happened in OTL with the Neo-Hittite States like Carchemish lasting until about 700 BC. But, I'm assuming you mean a united Hittite Empire lasting for that time. A POD could be the Hittites win the battle of Nihiriya.

A united Empire would have been a bridge between the Greek and Middle Eastern worlds. It could have had a different effect on the Trojan War. But they were never able to conquer Egypt or Assyria before, so I doubt they could in another three centuries.

It also might have kept out Phrygian and Armenian migrations so the history of the Caucasus is different, possibly with an Urartian-speaking population surviving.

Conquer Egypt, I doubt it. Assyria/Mesopotamia, maybe.
