Also Assyrian deportation policy was to deport the elites and some peasant farmers from one corner to the opposite corner of the empire. Some of the peasants were retained
They weren't spread across the eurasian continent but were sent to what is now sotuhern iraq or eastern Iran. Some assimilated and became ancestors of modern day Iraqis and Kuzestani Iranis and some came back with the Judeans after the Persian King Cyrus let people go back and the Iranis gave money for the rebuilding of the temple.

Thank you for your opinion (for whatever its worth)
I believe what the prophets wrote, not what vile men say.
