... 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.It is the representatives of Athens talking to the leadership of the neutral island nation of Melos. The words come to us via Thucydides' History of the Peloponnesian War. It is part of the "Melian Dialogue".
Part of American Exceptionalism is believing we don't operate the way Athens did. Plot spoiler: In the end, Athens loses, to Sparta, and the surviving people of Melos are restored, from exile, to their island.
