That is true and a big part of the reason why the world let the US get away with lots of stuff. But I think if the nature of the economical relation changes too much (ie: the US demand more juice to flow back to it), I can see how these countries might seriously consider (and maybe go for it) to break from the system. Will be a very wild ride.
