war is evil

I can't agree more with a statement in my life

War is necessary in some circumstances

Against violence, which is usually war, or will of war.
The war domino effect is more powerful than the nuclear one, because everyone has to agree to stop for like, forever.

Circumstances where the goal is further escalating a situation, destabilizing everything, committing genocide etc.

Or prolly saving a country

I don't think saving means what you think it means. War starts with small steps, one side against another until it escalates, there is no saving and no definetly no winner.

Well I mean you could still save the countries people
