1: Out of nowhere suddenly getting a say where there was none before and not much demand for it- that will make people happy
2:In the EU neither all people nor all countries have an equal say and it works fine.
1. I didn't say out of nowhere. Over a period of a hundred years there will definitely be a growing call for equality.
2.The eu is not a federalised empire. Each country in the eu is independent. It's a completely different scenario.
But generally as I said there's no real point in discussing whether or not everyone has an equal say and Indians somehow taking over and all that. An entire democratic process isn't going to be set up just to discuss defence matters. That's not something the public is generally given too much of a say in even with modern democracies.
The entire thing would have to be thoroughly undemocratic to work. Nobody whether they're in London or Nigeria is getting a vote.
1. Even if its out of the hands of common citizens each member state would need equal representation.
2. It might be a bit more than defence. At a federal level there'd need to be laws dictating trade and travel between different parts and a federal police force to enforce those laws. It might not have as much teeth as the federal government in the US, but it would still be there. Plus if diplomacy isn't being done at the federal level then technically each state would technically be independent seeing as they would have completely separate embassies to every other country. Then since the armed forces and other agencies cost money there'd need to be legislation dealing with taxes and a central treasury. Sure each member could technically finance there own forces, but then that would end up being less of a federalised empire and more of a confederation of member states.
