More specifically, I would LOVE if the long term dynamic became more of equal partnership and division of concerns - up to and including mutual basing agreements on BOTH sides of the pond.

We have Ramstein and Incirlik and Lakenheath and a bunch of others; maybe it makes sense for the EU to have a few disused bases in the US too - some joint, some just for them. Something in Texas, Alaska, somewhere in the PNW, East coast somewhere, Florida, and Guam would make a lot of sense, I think, even if (outside of Guam and Alaska, for somewhat obvious reasons), I would think they’d be largely training focused - but I think that sort of thing would be extremely helpful in terms of strengthening the alliance, and making the EU as a whole a much more obviously equal partner.
