The Tower of Babel–the first experiment in global government.
If you’re going to include within your country’s borders a whole raft of competing groups, some of which have a history of hating each other, there’s only two ways go go.
Either make everybody afraid to break the peace, in the face of the state’s overwhelming force; or everybody makes a commitment to the peace and order of the host country.
What? You mean you can’t just wander into a country and then demand they give you free stuff and change their own country to make it more like the hell-hole you just left?
When God split the human race into nations (Tower of Babel, Genesis 11), He saved us from the horror of a world government. We should be thankful for that!
