Military-wise Europe here is not a huger factor, more of a theatre of war, so realistically in order to choke America down you need to cut it off from its energy resources, which is problematic as of now. The US energy balance within its national borders long past its oil peak, past its gas peak few years ago, not a survivor on its own understandably. But let's brake down the US energy reserves outside of its national borders:
- Middle East -- the easiest part, a lot of regional allies, doable (well, if you consider THIS kind of scenario then that's doable).
- Western Africa, Nigeria -- already a problematic venture military-wise, but with applying soft power a doable scenario if European nations will play along here.
- South America -- practically not possible and not worth it.
- Canada -- a personal US oil colony, unrealistic, in few decades to come it's a bottomless oil barrel.
- North-Atlantic routes -- doable.
- Middle- and South-Atlantic routes -- problematic.
- Pacific routes -- unrealistic.
Not including nuclear energy here (biggest uranium mines and enrichement capacities are over here anyway) or any kind of other energy due to its small share, America is an oil empire down to its core.
But more importantly why would anyone would want that kind of military conflict? Personally my plans do not go any further than enslavement of Europe for now :D It's very realistic and beneficial, and taking in consideration the US position, could be mutually beneficial. I think we should be friends with the Americas (both of them). Was reading through Nyquist -- he was writing about some French "euroasianist" (not sure what's the word for him would be, but it's opposite of "euroatlantism" -- well, you got the idea) -- personally I don't need a philosophical explanation for why Europe must be enslaved, but if exists -- so be it.
Here's more or less an idea of my world:
