" In previous eras, national identities were forged because humans faced problems and opportunities that were far beyond the scopes of local tribes. Now, we need a new global identity because national institutions are incapable of handling a set of unprecedented global predicaments. We now have a global ecology, a global economy, and a global science, but we are still stuck with only national politics. This mismatch prevents the political system from effectively countering our main problems. To have effective politics, either we must de-globalize the ecology, the economy, and the march of science, or we must globalize our politics.

Since it is impossible to de-globalize the ecology and the march of science, and since the cost of de-globalizing the economy would be prohibitive, the only real solution is to globalize politics. There is no contradiction between such globalism and patriotism, for patriotism isn't about hating foreigners. Patriotism is about taking care of your compatriots, and in the 21st century in order to take good care of your compatriots you must cooperate with foreigners. So good nationalists should now be globalists. "
