What I don't understand is the concept of NATO or the EU: why would a group of countries willingly band together as "happy vassals," as the Belgian PM put it.
NATO: Russia is a threat to both Europe and the US, lets band together to make sure we can fight them.
EU: Europe keeps fighting wars, lets make our economies more inter-dependent so that doesn't happen as much.
For NATO, I can see the happy vassals thing (and that's what the Belgian PM was referring to), but can you explain who is the overlord in the EU example?
(This is mostly satire, even if I think 2 of the 3 second things were and are great ideas).
