I think you are right.
I think Damascus will be destroyed (Isaiah 17) by Israel using the "Sampson Option." Israel will only retaliate after WMDs are used against their homeland. Then, true hell will be unleashed. Isaiah 17 may or may not be part of the Psalm 83 war. The world will be so shocked at the exchange of WMD in the Middle East that they will demand a "world leader" sue of "peace."
You are correct.
