It’s not Armageddon yet. Hopefully the entire world is starting to unite against these monsters. Take them and the other groups like them and the world will be a better place. Syrians can have their country back.
Have India attack from the east thur Pakistan into Afghanistan and then onto Iran. Have Russia attack from the north thur Georgia into Azerbaijan then on to Iran to join up with the India army. Have the western powers (US,UK,France) attack from the west thur north Africa and then into Saudi Arabia. Turn the Israels loose on Palestine and Lebanon. Turn the Serbs loose in the Balkans. The three main armies join up in Mecca and then pivot north into Turkey. China gets Indonesia as a consolation prize. That would be my plan :)
