Lived through and ethnic cleansing genocide. I always laugh when western keyboard warriors start talking about how war is "needed" or "coming" and larping out their movie fantasies. Real war is nothing like TV. Its hell all around. There are no victors in war. Everyone loses.
War is sometimes needed; it's a necessary response to aggression. The genocides in Bosnia? Without a war, they would have murdered all the Croats. One of my teachers in school was a survivor of the Bosnian war, and her family absolutely would have been killed had they not gotten out. Without the Allied forces waging war against the Axis, Jews in Europe would have been completely eliminated.
The option to war is to curl up and hope that you can survive the bear mauling you.
War is never needed though, is my point. Yes unprompted aggression deserves a response (I'd never advocate for just laying down and taking the fascist boot), but war itself only produces destruction, broken homes, and broken families.
My comment was more about those who have not been through an actual war but romanticise it. There is nothing romantic about it.
