Yes - and the execution of most of the victors of Arginusae.
Re: Alcibiades, one reason he gets more favor in Thucydides's narrative than he otherwise might is because he was probably one of Thucydides's direct sources, what with both of them being in exile in the same region at the same time. Like fired coaches doing play-by-play commentary of their old team inevitably losing without them in the playoffs, only with all of their friends' lives at stake.
I recommended G.E.M. de Ste. Croix in another thread today, but also check out Jacqueline de Romilly if you can find anything of hers at your library. Her book on Thucydides and Athenian imperialism is a great antidote to the Cold War / neo-con American takes on the Peloponnesian War, and her read of Athenian foreign policy as a two-party binary of "pivot toward Persia" versus "pivot toward Sparta," with anti-imperialist voices completely silent, is certainly something that echoes today. It's also the best book for understanding Thucydides's relationship to Pericles (to respond to your other reply above).
