Vladimir Putin may have created a new superpower — and it’s not Russia. In the weeks since Putin invaded Ukraine, the European Union has changed. A recent New York Times opinion piece suggests the invasion has both united and militarized the EU (transforming it into a far more effective partner for the U.S). Europe could become an aggressive advocate for democracy, with power to rival China’s, as well as America’s. If so, how would this third superpower operate, given the EU’s decentralized structure? Europe’s own history offers an answer. The EU starts to look like the Holy Roman Empire.
Historians have never gotten together on a reason for the decline and fall of the Roman Empire. The question is more than just academic because the West’s great powers have often compared themselves to Rome and wondered if they might go the same way. Nowadays, the obvious comparison is with the United States. I’m going to describe the key theories for Rome’s fall and argue that even the good ones tell us little about America’s future.
