The History of the Peloponnesian War
Page: 241"Besides, for tyrants and imperial cities nothing is unreasonable if expedient, no one a kinsman unless sure; but friendship or enmity is everywhere an affair of time and circumstance. Here, in Sicily, our interest is not to weaken our friends, but by means of their strength to cripple our enemies. Why doubt this? In Hellas we treat our allies as we find them useful. The Chians and Methymnians govern themselves and furnish ships; most of the rest have harder terms and pay tribute in money; while others, although islanders and easy for us to take, are free altogether, because they occupy convenient positions round Peloponnese. In our settlement of the states here in Sicily, we should therefore; naturally be guided by our interest, and by fear, as we say, of the Syracusans. Their ambition is to rule you, their object to use the suspicions that we excite to unite you, and then, when we have gone away without effecting anything, by force or through your isolation, to become the masters of Sicily. And masters they must become, if you unite with them; as a force of that magnitude would be no longer easy for us to deal with united, and they would be more than a match for you as soon as we were away.
"Any other view of the case is condemned by the facts. When you first asked us over, the fear which you held out was that of danger to Athens if we let you come under the dominion of Syracuse; and it is not right now to mistrust the very same argument by which you claimed to convince us, or to give way to suspicion because we are come with a larger force against the power of that city. Those whom you should really distrust are the Syracusans. We are not able to stay here without you, and if we proved perfidious enough to bring you into subjection, we should be unable to keep you in bondage, owing to the length of the voyage and the difficulty of guarding large, and in a military sense continental, towns: they, the Syracusans, live close to you, not in a camp, but in a city greater than the force we have with us, plot always against you, never let slip an opportunity once offered, as they have shown in the case of the Leontines and others, and now have the face, just as if you were fools, to invite you to aid them against the power that hinders this, and that has thus far maintained Sicily independent. We, as against them, invite you to a much more real safety, when we beg you not to betray that common safety which we each have in the other, and to reflect that they, even without allies, will, by their numbers, have always the way open to you, while you will not often have the opportunity of defending yourselves with such numerous auxiliaries; if, through your suspicions, you once let these go away unsuccessful or defeated, you will wish to see if only a handful of them back again, when the day is past in which their presence could do anything for you.
