We never used to blink at taking a leadership role in the world. And we understood leadership often required something other than drones and bombs. We accepted global leadership not just for humanitarian reasons, but also because it was in our own best interest. We knew we couldn't isolate ourselves from trouble. There was no place to hide.

We don't have to sit by and watch our meritocracy be replaced by a permanent aristocracy, and our democracy be undermined by dynastic wealth.
