Not unlike how the 2020 work from home shut down many businesses and demonstrated how much infrastructure is dedicated to travelling between two arbitrary places rather than for living. Businesses that exist to serve bases would shut down (ghost towns eg Rammstein) on both sides of the border - USA has a lot of businesses that sell things mostly to supply a base on the other side of the world with limited practical uses in the USA. Jet fuel demand etc would be reduced. We’d start hearing again about the enormous piles of [toxic] garbage the USA military leaves behind.
Fuel usage would probably be up, as the USA would have no nice spots to from where project power. They’d probably have to boat stuff everywhere all the time at huge costs.
Many places also use the US military as a deterrent in lieu of having their own defense. Poland just requested a large US base to deter Russian invasion. South Korea would certainly be in trouble if we left.
