More killing. Less good deeds

[William F. Owen]

"War is war" is a tautology of the form X = X. It is also a logical fallacy that confuses the sign with the signified in that [INDENT]if killing is involved, and
war is killing, therefore
this is war

.... but that is not what "War is War," has ever aimed to impart.
War is war is an aphorism that correctly observes that that war has an enduring and fundamental nature, that has not changed over time. Thucydides and Clausewitz wrote about it, and did so usefully and accurately.

As Clausewitz, Foch and many others have said, "beware the people who tell you that you can have war without killing."

If that is wrong, then please show me how?

That is also why war must be armed social science.

How can a social science be aimed primarily at breaking the will of the enemy?

Putting in place all the humanitarian and social programs aimed at the civilian population, probably is social science, but that it does not break the enemies will to endure, in the same way killing him does. No social science has ever been founded on telling someone "do what we tell you to improve your life or we will kill you."
