My guess is as good as anyone's. But I think NATO was used as an excuse for war because it's a military (although defense) alliance. It would be impossible to justify war for country joining the EU.

As for the golden ticket metaphor, I agree, but when the country is so economically and institutionally behind than the rest of the EU, this would still benefit them a lot. All Eastern countries experienced big emigration but a lot of the citizens previously having emigrated are now returning.
