"So many people quote the famous line from Thucydides—'The strong can do what they can, and the weak must suffer what they must'—and forget that the amoral imperialists who used that line in the end lost their war and their empire. 

    "Thucydides does not offer the line, 'The strong do what they can,' as a neutral analysis of how international affairs operate. He offers it as an expression of the reckless arrogance that brought about the destruction of the Athenian Empire."

~ David Frum

"Thucydides is often interpreted as the proponent of power politics .... However, again, a careful reading of the text reveals a deeper ambiguity. Is Thucydides genuinely teaching that might makes right or is he more interested in illustrating Athenian hubris or both?”

~ Franz-Stefan Gady from his article 'Hey Policy Wonks, This Is How You Should Read Thucydides'
