If they make war against God, every person of their country is doomed.
But you’re the one who wants to make war against their God (which happens to be the same God of the Jews and Christians).
I'm sorry, their "God"?
Their "God" is Satan.
As long as the people are following this "God", the law on the matter is clear.
Now go, attack the Amalekites and totally destroy all that belongs to them. Do not spare them; put to death men and women, children and infants, cattle and sheep, camels and donkeys
What was Amalek's crime? Was God racist against them? No, they were at war with God and his people. When Israel was leaving Egypt, just to be shits, they attacked them. The evil of Amalek was so profound that even cattle and sheep were evil. When an ideology pits people against God, it has to be done away with. You first ask if they really want war, or if something can be negotiated. Then if you can, killing one or two people, if the people repent and turn away from their beliefs, all is good. Then you have to kill all warriors. Then if even the women, children, and animals are against you...
You have to stop them all. Iran isn't like that. They have admitted they want their clerics gone. Palestine is. I would that Palestine be given a land of its own, but I fully expect their men, women, children, and animals to continue against Israel. They play the blame game.
It’s almost as if Bulma doesn’t understand the concept of line of succession or the power of martyrdom. Sure, let’s give Iran lots of martyrs, nobody is going to want to step up and avenge them. 
I do actually. Martyrs believe in a cause because they are fed rhetoric.
And when the leadership is out of power, this happens.
The English and Germans realize they aren't the enemy. Had the war ended on Christmas Day, this world would not have a World War II, no Cold War, etc. The war machine sent its "Christian" priests to tell everyone that this was the enemy. They sent their military generals to relieve everyone involved and send a bunch of green troops to continue the fighting.
When you stop being propagandized for a hot minute, the chain of command falls apart, and the war machine ends. Kill the war priests, and it's all over. Like a bad dream. The Muslims are just led by generals, and they lose their fervor for martyrdom. They think about how their priests died like other men, and they realize there is nothing special about Islam.
