If it's anything like the European Union then I'm all for it. Would be tough at first but I'm all for unification, if done correctly. It's not like our separate cultures can't thrive
within a union. An example is Quebec within Canada; classified as a nation within a nation. Quebec is very unique and has a culture of it's own yet it's still part of Canada. For now at least lol.
