When Nolan’s Odysseus recalls the sacking of Troy, he blanches at the memory of 10 years of rage pouring into a city in a single night. It was hard for me not to think, then, of the pent-up rage that Hamas poured into Israel on Oct. 7, 2023, and that Israel has poured into Gaza a hundredfold in the years since. The Israeli prime minister, Benjamin Netanyahu, now describes Israel’s future as “Athens and super-Sparta.”

Yuval Noah Harari, the Israeli-born historian who wrote “Sapiens,” sees the diminishment this foretells clearly. “A lot of the thinking, and also the practice, about what it means to have freedom of thought, what it means to be a powerless minority, was done by Jewish thinkers,” he told me. He added:

For 2,000 years, Jews all over the world saw studying and learning as the highest spiritual activity. After 2,000 years, you ask them: What have you learned? You have studied for 2,000 years. What have you learned?

And then people like Netanyahu tell you: Oh, we have learned that you need to be a Roman, that you need to be strong, that you need to build legions, that you need to destroy cities. This is the only thing that matters in life.

It’s a legitimate value system. Rome had its usefulness. But if after 2,000 years, the Jews simply become the Romans, what was the point? Why did you waste 2,000 years, then? You could have just become Roman back then.

This is Nolan’s finest trick: to make one of our oldest moral rules sound new again. To turn the best of Judeo-Christianity into the law of Zeus, so we can see why it might matter and what it might still have to say to us.

What Odysseus sees, eventually, is that his violations of the moral order have brought ruin to all around him. Agamemnon, the king who launched the war against Troy, is dead, his throat slit by his wife, who never forgave him for sacrificing their daughter for fair winds. Troy is destroyed. Ithaca, Odysseus’ home, is overrun by suitors who seek his wife and land and think nothing of murdering his son in their pursuit. Odysseus and his men were not fighting the barbarians; they were the barbarians. And their actions led to more barbarity.

So, too, has the political movement that rose promising to make Western civilization great again betrayed its inheritance. The world now looks at America and sees us as the barbarians: the country obliterating the global order, the country that takes what it wants and demands tribute from those who cannot resist.

And what the political opposition has to do now is recognize what Nolan recognized: That it is an affirmation of our civilizational values to say that cruelty is a weakness. That only compassion and reciprocity build a durable and decent society. That order is necessary but order without ethics and restraint is perversion or authoritarianism. That there is both beauty and wisdom in the injunction to avoid inflicting on others what we would not see turned against us and in remembering that we were strangers in the land of Egypt, too.
