Same. The whole European army thing seems sensible as well.
Ireland has a history of neutrality which im quite fond of but I agree, think its a much harder sell than cooperating elsewhere and I'm not as convinced but agree overall. Realistically if were invaded an army made of european nations are probably (hopefully) going to show up to protect us. We can contribute to that financially if nothing elsee.
I suppose because a European superstate would involve more than just the things you mention.
It doesn't need to. Thats a lot of stuff we could cooperate on that I think is pretty hard to argue isn't in our mutual interest.
