You mean how Caesar used swords and fought against the legal authority in the Republic to name himself dictator? Thank you for proving my point. It doesn't matter in the end. The victor will always paint themselves as just and righteous and civilized, and the defeated will always be portrayed as unworthy, deficient, a menace to be crushed. Unfortunately for you, your constant whining is public record, so you won't be afforded even that small dignity. War is not glamourous. It has no glory. It's messy, and the belligerents will win however they must.
A small history lesson: the 'barbarians' won in the end. You're speaking their language.

But you know how this goes. You just pretend honour matters when things go against you.
