Do you agree or disagree with this statement The Athenians brought the Peloponnesian War on themselves. Defend your argument?

I agree that the Athenians played a significant role in bringing the Peloponnesian War upon themselves. Their expansionist policies and aggressive Imperialism, particularly through the Delian League, antagonized Sparta and its allies, creating a tense political environment. Additionally, their actions, such as the Sicilian Expedition, demonstrated overreach and a disregard for the balance of power in Greece, ultimately fueling hostilities that led to war. While Sparta and other factors contributed to the conflict, Athenian decisions were pivotal in escalating tensions.
