The parallels are not exact, but nonetheless striking. Taiwan is next door to and deeply entangled with China in its history and culture, just as Ukraine is uniquely entangled with Russia. Seeing Taiwan and China (like Ukraine and Russia) as simply random sovereign states with a right to self-determination under international law is correct, so far as it goes. It’s also moral — as majorities of both Ukrainians and especially Taiwanese want independence and have constructed nascent democracies in the wake of autocracy.

But the nationalist passion Russia feels about Ukraine and China feels about Taiwan is real, visceral, and hard for outsiders to understand intuitively. The sense of a rogue region that somehow got away from the homeland is vivid among Russian and Chinese nationalists. This kind of understanding — claiming a “sphere of influence” — is now deemed reactionary by the West’s foreign policy elites, as, perhaps, it should be. But that doesn’t mean that everyone, especially China and Russia, have actually moved past it. Even Americans have very different emotional responses to perceived threats in our own hemisphere compared with the rest of the world. So this is also a culture clash of sorts — globalism and the nation state vs nationalism and spheres of influence.

I’m not saying that this belief in a sphere of influence is a universal view in Russia or China — or that it is justifiable. I’m just saying it is real. And I’m not excusing Putin or Xi from taking a particularly zealous view of this irredentist nationalism, which they both do, for their own personal and political advantage. I’m just noting how national pride deeply informs them, that resentment of the West consumes them, that a sense of historical grievance spurs them on — and that they are not outliers among their compatriots. It is crazy to underestimate the power of this kind of revanchist nationalism — among rulers and ruled. And I fear we underestimated it in the case of Putin.
