Tribalism is the root of all wars.

Nationalism among nations is like racism among races. Racism and nationalism are forms of tribalism. Tribalism always, always leads to war. Why? Because every nation thinks they're superior to other nations, and their own self-interest is more important than the self-interest of other nations.

North Korea, the Democratic People's Republic of Korea, isn't democratic. The Nazis, the National Socialists, weren't socialists. And America isn't the land of the free. It's all just clever nationalist marketing.

If you like war, be a nationalist. If you like peace, be a citizen of the world.
