How interesting! Some believe that the war of Psalm 83 will be started by an attack with chemical weapons after which Israel will retaliate with nuclear.
True. Those "some believers" are kooks who hate the Bible and love FUD.
Ps 83 refers to 2 Chronicles 20, the confederacy against Jehoshaphat. Those kooks are only a few thousand years off on their "prophecy". And what fool thinks that after God said that He would destroy Assyria and Philistia (see Isa 14), and indeed He has, that somehow these destroyed nations are supposed to resurrect like zombies and play any future role in world events?
Chemical and nuclear weapons? Really? What must it be like to hate God so much that one spends time ridiculing it and telling these insane lies? I hope you find a better lot of friends than the ones that are feeding this garbage into your brain.
