In January, the New York Times asked President Donald Trump if there were any limits on his global powers. That was eight months ago, but fortunately Christopher Nolan’s blockbuster adaptation of “The Odyssey” has made ancient Greek literature newly relevant. The hubris of the suitors, and at times Odysseus himself, invites punishment by the gods and their mortal instruments. The limits on Trump’s power have been exposed by far less august forces than the combined might of the allies in World War II or the fearsome Russian winter. But the regime’s ability to absorb punishment while imposing its will on the Strait of Hormuz has proved to be a greater constraint on Trump’s power than his morality or mind.
