Has seeing the horrors of the Ukraine war made you want the west to stop it and force a surrender? More horrors don't make people want less war. If anything, it may be the opposite. People pretend to be anti-war right up until there's a war and then suddenly it turns out they're actually anti-losing-the-war.
I want less war. I'm against attacking other countries, but totally in favor of defending yourself if you get attacked. Those aren't contradictory statements.
Surrendering to an aggressor will let the aggressor get what they want, hence making war more appealing. So it's coherent for anti-war people to resist and make it as hard as possible for an aggressor. Even Gandhi justified defensive war.
