How does Kagan’s interpretation differ from Thucydides’ account?

While relying on Thucydides, Kagan challenges his deterministic view, suggesting key decisions—like Athens’ Sicilian campaign—were avoidable missteps. He also questions Thucydides’ reliance on Alcibiades, an Athenian traitor, as a source.
