2/2
This is their logic using the example of Damascus:
P0: The Word of God is true.
P1: The Bible is the Word of God.
P2: The Bible says, "Damascus will cease to be a city and will become a heap of ruins." ESV
P3: Damascus has not yet ceased to been destroyed.
C1: Damascus will be destroyed before the end of the world.
Because they think the nation of Israel is the Biblical "Israel", if the nation is ever destroyed, then Premise 1 is false, and their religious identity collapses.
