The point of war is enforcing your will through violence. You can skip the violence, but then bullies would essentially be unrestricted.

There's no single point to war. It can be anything from enjoying the destruction and killing and torture and lack of rules, to "retribution" (for people who are into thinking of other people in terms of arbitrarily and vaguely defined groups), though creating chaos to get political advantage, to distraction from political issues, or really whatever...

"War" for the sake of "war" is pointless. It should be tied to a political objective for some kind of gain.

Ideally, it would be the last resort in limited capacity when diplomacy fails.

Otherwise you're unleashing horrors on humanity.

Do you think there is a difference between killing people and violence ?
