Jeremiah 49: Many countries will be destroyed

 In Jeremiah 49 we read many prophecies against many nations and cities: Ammon, Edom, Damascus, Kedar, Hazor and Elam. It seems to me that the cause of the great destruction to so many places is the same: the Babylonians will invade and take everything. It reminds me the flood in Noah times: a great destruction to many places. It is interesting what the Lord says about Ammon:

4 How you boast about the valleys!
Your valley is flowing away,
You backsliding daughter
Who trusts in her treasures, saying,
‘Who can come against me?’

I know that the Lord calls Israel his son in many verses, but it surprised me that He refers to Ammon as a "backsliding daughter" who trusts in her treasures. The Lord says:

6 But afterward I will restore
The fortunes of the sons of Ammon,”
Declares the Lord.

It seems that after the exile, Ammon will be restored, as Judah. Some other countries were not restored, as Elam.
