Actually, that’s one of the fun problems the EU is about to have. They have relied for so long on the US military as their shield that they were able to take most of the money they would have spent on defense on social programs. Now the US is pulling back and highly unlikely to be able or willing to defend Europe, especially as pretty much everyone in the US is tired of foreign wars. Even more especially if we appear to be doing all of the heavy lifting yet again.
Once that finally sinks in, Europe is going to have to choose - socialist feel good programs or national defense. I await the shrieking from Euro-lefties either way. :D
The “Euro-righties” are nothing like American conservatives though; they are more like those lefties in a lot of ways. They are no more worthy of power than the lefties.
