History of the Peloponnesian War

And since we be come to this, which once before we said at Lacedaemon, that everyone ought to proceed as he shall think good against his own confederates, we claim that liberty now of you; and that you that have been helped by our votes will not hurt us now by yours, but render like for like;

remembering that now is that occasion wherein he that aideth us is our greatest friend, and he that opposeth us our greatest enemy; and that you will not receive these Corcyraeans into league against our wills nor defend them in their injuries.

These things if you grant us, you shall both do as is fit and also advise the best for the good of your own affairs.

This was the effect of what was spoken by the Corinthians.

Both sides having been heard and the Athenian people twice assembled, in the former assembly they approved no less of the reasons of the Corinthians than of the Corcyraeans. But in the latter they changed their minds, not so as to make a league with the Corcyraeans both offensive and defensive, that the friends and enemies of the one should be so of the other (for then, if the Corcyraeans should have required them to go against Corinth, the peace had been broken with the Peloponnesians), but made it only defensive, that if anyone should invade Corcyra or Athens, or any of their confederates, they were then mutually to assist one another.
