Thanks for the insight. I don't disagree your point per se. If war could be accomplished without further harming those citizens then I might agree. Or if war brought about positive change then maybe you could justify the means. But sadly we've seen time and time again that destabilising governments through instigating war - even horrible despotic regiems like the aforementioned - usually ends up with more long term conflict.
I should add that I'm against starting wars but not against retaliating, even ending the war, if and when required.
