The rest of the point aside, you're trying to tug a heartstring based on a stereotype. This is much more condescending and out of touch than it is accurate with regard to the modern US Military.
My entire extended family has connections to the military. I grew up on Army bases. I know friends who enlisted and others who did ROTC. I nearly did Air Force ROTC myself for purely financial reasons (ended up going to a cheaper school, still paid for largely my father’s post-9/11 GI Bill benefits). I’m familiar with the subject matter. Access to Tricare and the VA hospital system is a big part of the military’s recruitment appeal.
But historically NATO has been a pretty good deterrent against war. Should we stop that?
As for the troops from various NATO rotating through eastern NATO countries: I really hope nothing bad happens, and they experience some new culture.
