The relevant quote:
On the surface, this doesn't particularly concern me but then I thought about it and I started wondering. If we're demanding that these countries pay us for our troop presence, are we obligated for a certain level of time or specific level of commitment for that?
Say that Country X pays us $Y millions for U.S. troop presence. Can we just up and leave the next day or are we committed to be there for a specific amount of time, defend against specific types of threats, that sort of thing? Does Congress have to approve this or just the C-in-C. And if the C-in-C approves it, can Congress ever terminate the relationship?
I don't know how that works. Can someone explain?
