“Invading armies would be too spread out at a distance for the nukes to have the desired effect.”
Why would an army invade Israel? The military has missiles now. Even Iran is counting on missiles to destroy Israel, and they can mass an army inside their own borders close by. Why go to all that trouble when a few missiles is all it takes?
No invading army splits their forces. General George Custer tried that.
The Bible says Israel will be INVADED, not simply destroyed.
