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.
