How much longer can that keep up until we see some sort of strange Balkanization and increased secretarian violence. I don’t see how we can keep up the facade of a united nation where more or less two factions bubble up that are clearly opposed along irredeemable lines (personally I believe there are more than two factions but they tend to bubble up and ally into just two in a way that makes differentiation basically meaningless)
