I'd rather have the money flow going to our own nation opposed to a bunch of other nations that don't give a watermelon about us in the first place.
Though it'll probably never happen due to some of the strategic locations we are in. I'd like to see bases outside the US that are in countries that despise us and constantly bich about us get shutdown. Remove all those jobs given to the locals by our government.
Take all the money the bases bring into their economies yanked with little to no notice.
Bring that money to other surrounding countries that really give a watermelon and watch the old base "communities" whine and cry about how ruthless and uncaring the US is.
I don't know how the Navy guys are but if they are anything like some of the Marines I've been stationed around they normally bring it on themselves. When I was stationed in NC not only did my base make it illegal for the Marines to use certain facilities on base but so did the local and surrounding communities. If you even looked like a Marine they would start to turn you away until they found out you were Air Force. I had multiple occassions where I was about to be refused entry to clubs and bars because of my high and tight. I showed them my ID and they apologized and let me in. A few places had signs posted on the front doors saying Marines were not allowed in the facility.
