During this Greek civil war, which lasted decades, the Spartans took a large army and stood outside the walls of a city. The leader of the Army, Brasidas, probably the General most respected by non-Spartans during the entire war, allegedly spoke these words:
Some of you may hang back because they have private enemies, and fear that I may put the city into the hands of a party: none need be more tranquil than they. I am not come here to help this party or that; and I do not consider that I should be bringing you freedom in any real sense, if I should disregard your constitution, and enslave the many to the few or the few to the many. This would be heavier than a foreign yoke; and we Lacedaemonians, instead of being thanked for our pains, should get neither honour nor glory, but, contrariwise, reproaches.
This, perhaps, reminds you of Iraq.
