For if while still unprepared, hurried away by the complaints of our allies, we are induced to lay it waste, have a care that we do not bring deep disgrace and deep perplexity upon Peloponnese.
Complaints, whether of communities or individuals, it is possible to adjust; but war undertaken by a coalition for sectional interests, whose progress there is no means of foreseeing, does not easily admit of creditable settlement.
And none need think it cowardice for a number of confederates to pause before they attack a single city.
The Athenians have allies as numerous as our own, and allies that pay tribute, and war is a matter not so much of arms as of money, which makes arms of use. And this is more than ever true in a struggle between a continental and a maritime power.
