What do you call a group of nations that squabble with each other, have a terrible rate of economic growth, and nothing much in common except a desire to band together to provide a counterweight to existing global superpowers? And that despite this utter lack of common ground between existing members, they actually want to add new members.
Depends. In the 1960s you’d have called it the Non-Aligned Movement. These days, you’d call it the European Union.
