Destroy it from the ground up.
Kill every party member, every general, every politician, every civil servant, every cabinet member, every advisor. Their families. Their friends. Their pets. Leave a personal trail of darkness and terror stretching across continents as the lights of civilisation flicker, wink out and die, to be replaced with the inferno of chaos and anarchy. Bridges crumble into dust. Powerplants erupt into great, monstrous coloumns of fire. The death throes of weapons stores obliterate entire city blocks, leaving naught but ash and dust.
Then, I will start recruiting.
