On the one hand, we have Denmark that got almost as generous opt-outs from various EU duties as Britain. Then we have Norway that never joined at all. Then we have Sweden that has no opt-outs, but didn't join the Euro anyway. And the Danish people said Nej! in a referendum about partaking in Europol.
What if only Britain and Ireland joined the ECC in 1973, but Denmark would've said Nej! just as much as Norway?
How would it have affected a 1995-style enlargement after the end of the Iron Curtain and the evolution of the ECC into the EU as per OTL?
