“Globalization in particular is a tide that is impossible for any ruler to order back. Many of a country’s problems are inherently global, including migration, pandemics, terrorism, cybercrime, nuclear proliferation, rogue states, and the environment.

Nor can the benefits of globalization—more affordable goods, larger markets for exports, the reduction in global poverty—be denied indefinitely. And with the Internet and inexpensive travel, there will be no stopping the flow of people and ideas (especially, as we will see, among younger people). As for the battle against truth and fact, over the long run they have a built-in advantage: when you stop believing in them, they don’t go away.”
