>> It can also be taken to mean that Syria itself will lose it’s crown, or that Syria will cease to be as a sovereign nation for all time. <<
Once Damascus fell, Syria never became its own nation again until 1945... about 3,000 years later. And in that time it has been dominated by the Soviet Union, Egypt, and Iran.
I could argue that even as it was dominated, Syria has almost always retained it's identity. It's usual state of existence has been as a vassal state through Rome and Alexander, the Selucids, Egypt, etc.. Even during the Ottoman empire the area was still known as Syria, and it was almost always governed from Damascus or from Antioch.
But all of that is beside the point- as the prophecy against Damascus suggests utter destruction for all time... Yet here it is... Syria is sovereign, and Damascus is inhabited.
It's existence suggests the prophecy is not fulfilled.
