I think that folks nowadays have a mistaken picture of war.
War differs from police activity.
War differs from a battle.
Most of history deals with wars that include seige warfare.
Read about wars in history. They basically don’t take prisoners. The Geneva Convention was aimed at taking away some small amount of of the barbarism toward civilians.
I posted this earlier; situations where God … OUR God directed total warfare to groups, nations, tribes, that He picked out. For His own reasons:
Read the Old Testament. Where God personally directed the Prophets to give very specific directions to the leaders of the Twelve Tribes of Israel. God ordered the total destruction of their enemies.
Read “The Prophets” by Norman Podhoretz … chapter two: “Wielding the Sword”.

Joshua at Jericho and at Ai. And God hurling hailstones down upon the Amorites. Conquest after conquest.
Moses smote the two kingdoms ruled by Sihon and Og.
Gideon against the Midianites and the Amalekites and the children of the east. Gideon was given the “nickname” of Jerubaal … “contender against Baal”. [Baal was a false god,]
In Judges, there is Jephthah against the children of Ammon.
And then there is God speaking through Samuel to Saul: “Now go and smite Amalek, and utterly destroy all that they have, and spare them not; but slay both man and woman, infant and suckling, ox and sheep, camel and ***.”… But Saul defeats the Amalekies and disobeys God … allowing their king, Agag, to survive and allows the troops to take as spoil the best of the Amalekites sheep, oxen, fatlings and lambs … and would not utterly destroy them.
God then reminds Samuel, He has in the past vowed to wipe out the Amelikes because of the cruelty they showed toward the Israelites fleeing from slavery in the desert.
The failure to carry out God’s battle command caused Israel to be punished.
“And the Lord said unto Moses, write this for a memorial in a book, and rehearse it in the ears of Joshua: for I will utterly put out the remembrance of Amalek from under heaven. And Moses … said … the Lord hath sworn that the Lord will have war with Amalek from generation to generation.”
Podhoretz’ book is filled with examples of fights to the death between nations.
We need to be careful of taking situations out of context.
War is unique in that it is utterly destructive. War is not a contest. It is a fight to the finish.
War is deadly to nations. When one ruler of a nation starts a war they had better be prepared to win or suffer the consequences of utter defeat. And some of these wars take years, decades and generations to finish.
Someday the lion will lie down with the lamb.
But not yet.
