But if they had begun with us, while all the states still had their resources under their own control, and there was a center to rally round, the work of subjugation would have been found less easy.
Besides this, our navy gave them some apprehension: it was always possible that it might unite with you or with some other power, and become dangerous to Athens.
The court which we paid to their commons and its leaders for the time being, also helped us to maintain our independence.
However, we did not expect to be able to do so much longer, if this war had not broken out, from the examples that we had had of their conduct to the rest.
How then could we put our trust in such friendship or freedom as we had here? We accepted each other against our inclination; fear made them court us in war, and us them in peace; sympathy, the ordinary basis of confidence, had its place supplied by terror, fear having more share than friendship in detaining us in the alliance; and the first party that should be encouraged by the hope of impunity was certain to break faith with the other.
So that to condemn us for being the first to break off, because they delay the blow that we dread, instead of ourselves delaying to know for certain whether it will be dealt or not, is to take a false view of the case.
