Damascus Countdown pt 2

What if Iran gets an atomic bomb or already has it? Would Israel launch a preemptive strike against Iran? What happens if Israel is then overwhelmed with a massive retaliation from the entire Muslim world and one of thousands of missiles is atomic? Joel Rosenberg, author of Damascus Countdown, says Isaiah 17 prophecies that when the nations come against Israel, God will defend Israel and Damascus will cease to exist as a city.
