Was the war between Athens and Sparta Inevitable?

I think that the war between Athens and Sparta was inevitable.think that they were both dragged into the war with each by different states. Athens was dragged in reluctantly by Corcyra to help them defeat Corinth. Pericles sends some ships, but they were defeated with Corcyra by the Corinthians and their allies, so Athens punished their allies by blocking their trade. The allies (Megara) in turn ask the Spartans for help, and then the battle between Athens and Sparta starts, so I think it was not their own faults.
