Thucydides gave the following version of the ultimatum that the Athenian Empire gave to the small island city-state of Melos demanding it’s unconditional surrender to the Athenian Empire even though Melos had taken the utmost care to be Politically Correct and offend no belligerent during the Peloponnesian War:
”We shall not trouble you with specious pretenses-either of how we have a right to our Empire because we overthrew the Persians or are now attacking you because of wrong you have done us – and make long speeches that would not be believed……In return, we hope that you, instead of thinking to influence us by saying that you have done us no wrong, will aim at what is feasible…….Since you know as well as we do that right, as the world goes, is only in question between equals in power, while the strong do what they can and the weak suffer what they must.
The small, independent, idealistic, island city-state of Melos rejected the Athenian Empire’s ultimatum. The Athenians then promptly wiped Melos off the face of the Earth and the Melians simply ceased to exist.
Moral of the Story:
Idealistic, Kum-Bah-Yah, give-Peace-a-chance Liberals don't survive long in the Real World unless their society has a potent Army manned by un-Progressive, Politically Incorrect, war-mongering Conservatives to protect them.
