Those bases in the EU aren't just there for the benefit of the EU, that's what everyone has been trying to tell you all since you started crying about NATO countries not paying enough for defense.
If you want to project force all the way around the world, then you have to have a logistics system capable of supplying your military, and those bases, and ports that we have access to are integral to being able to do so.
Cruise missiles, not ballistic, I mispoke, and we do it all the time. Rota is the largest NATO munitions and fuel depot in Europe.
Even if you stop "bombing for oil" then you still have to have forward logistics for a viable deterrent for countries like Russia or China, unless it's your plan to go full isolationist and pull back all USN forces to operating in or near US territorial waters.
