What gave you the impression that EU members hate each other? It'd be a weird union if that was the case. Not saying it's not possible, I just haven't seen it myself, although I am a Swede so clearly I do hate the Danes and the Norrbaggar with passion, but it's love-hate, not hate-hate.
If we're talking about leaders for member states, then they're doing their job right :) They're not meant to figure out what's best for the union, we have separate elections for those people who go to EU and represent the country + care about the union. The national "leaders" of the country are quite expected to put national interests above what's best for the union :)
Still, love em, let the weirdos eat their snails in peace and may we always be brothers and sisters <3
A Dane.
I see how it may look like this from the outside. But I think it would be like saying that siblings hate each other because you witnessed an argument.
Most people in most EU countries consider the other EU countries as allies, even though they don't agree on everything. Now the fact that 27 countries argue means that they talk to each other. I think it's a lot less polarised than in the US. Or course there are extremes too.
On the positive side, this shows that the EU has gained a level of international influence that is taken very seriously by other major powers. It's not 100% certain that it will survive this current wave of assaults, but if it does, it will be even stronger.
That is also why the nationalists inside of Europe want to be friends with those other players: because if you want to make Europe weaker (because you think you are better off on your own as a European country), then your interests align with those other players.
Let's not pretend that nationalism doesn't have deep roots in Europe.
In the us these groups have just stopped talking to each other. The only time that happens is over Thanksgiving and that's when it stops for some of those conversations.
At least in Europe the split is usually not within families...
Are you referring to the time when the world Cup is going on? In that case, absolutely. We all turn into monkeys climbing onto our own rock lol
