As we understand from the archeological excavations, our Assyrian friends formed a trade road between Mesopotamia and Syria. Maybe you heard about Kanesh before. Kanesh was the capital of Assyrian Trade Colonies and it was within the boundaries of Cappadocia. When Assyrians were living in Cappadocia, they gained a lot of favor from this region but the thing that they didn't know, actually they were helping Hittites. Don't get me wrong, I am not underrating their existence. Solely the other civilizations which came right after, they lived in these lands much longer, stronger and wealthier. Mine is just an analysis.
