With Russia fighting with the EU, this is a good one.
US+Mexico+Canada though has a massive amount of resources and could pretty well survive without help from the outside world while I think the EU would have to rely too heavily on russia and the outside world to support them. And NA would be more unified, The US has more modern military experience than any country in the world atm and a good chunk of the EU is going to be fairly useless militarily. + thy've been spying a shit ton on the entire world for a while now so they'd know a lot of weaknesses to go after right away.
We'd at least get to see all those secret weapons the US has.
