The global treatment of Russia may well mark the most profound of all of these shifts. It’s the world’s largest country by geography, an oil and gas powerhouse with the globe’s largest nuclear arsenal. Nevertheless, a curtain is descending around it, disconnecting Russians from globalization’s benefits, such as trade, travel, finance, and technology. The result will be a poorer, more isolated, and weaker Russia. Governments are no longer trying to alter Russian behavior but are instead trying to diminish its ability to project power.

We can’t be certain which of these momentous changes will ultimately stick. The war and the reactions to it remain in their early days. No one can say definitively what kind of world will emerge from the ashes in Ukraine.

But some geopolitical outlines have already come into focus, and they are drastically different from the old ones. Lenin reportedly once said, “There are decades where nothing happens, and there are weeks where decades happen.” This is one of those weeks.
