Coincidentally, this whole Russia Ukraine war has pushed most NATO nations to build up their military and re-arm. If Europe can actually defend itself, the US's obligation there reduces significantly.
Yeah and it's much cheaper to operate locally and defensively than it is to have a very expeditionary and overseas force the US has so they /could/ close the capability gap for less money. There is a bit of difficulty having so many different militaries needing to work together but it's something that works with practice.
