You might want to check out Robert Kaplan’s interesting essay on Thucydides, Hobbes, and the distinction between the pretexts for war and its reasons especially as it applies to the tense situation in the Far East.
It also presents me with an opportunity for returning to a subject I’ve commented on before here. There is no single, authoritative manuscript for Thucydides’s The Peloponnesian War and, importantly, no contemporaneous one. What we have has been pieced together from fragments, most of low quality in completeness, accuracy, and integrity over the period of more than a millennium by a variety of unknown editors. We have very little idea of what the original work was actually like.
It is wrong to think of The Peloponnesian War as history. It’s a group essay.
