History of the Peloponnesian War

The return that you made them was therefore neither equal nor honorable, since you called them in, as you say, because you were being oppressed yourselves, and then became their accomplices in oppressing others; although baseness rather consists in not returning like for like than in not returning what is justly due but must be unjustly paid.

Meanwhile, after thus plainly showing that it was not for the sake of the Hellenes that you alone then did not Medise, but because the Athenians did not do so either, and you wished to side with them and to be against the rest;

you now claim the benefit of good deeds done to please your neighbors. This cannot be admitted: you chose the Athenians, and with them you must stand or fall. Nor can you plead the league then made and claim that it should now protect you.
