If it makes you feel better. The US government looks like it might start removing some of the 28k troops that are stationed in South Korea over this. No reason to keep them in a country that enables this sort of behavior.
The US troops are more likely there as a political shield. Indiscriminate bombing would kill them too, hence drag the US into war so any enemies of S Korea have to act judiciously.
If anything more foreign bases will be closed in the upcoming years to reign in the reckless spending + endangerment by the DoW. It's not only politically easy, foreign bases don't have representation in Congress, but it's a great to sell alternative governing visions (less on foreign imperialism vs more domestic spending).
That's why Japan and Germany are some of the worst places to live in the world. Oh wait, I had that quality of life chart upside down.
