Hi SetApart,
It could be as I am not sure the actual order of defeat exactly. I know basically every current neighbor of Israel is mentioned as receiving punishment from the Lord. Damascus is specifically doomed and still a city today. Most people think Damascus is destroyed prior to or at the beginning of the last 7 years. I think otherwise as do you. Check out Joel 2&3 they are about the same story as well.
Peace,
Seeker
