There is no way "United States" can change its mind during an international negotiation independently of any of its representatives. This is provably false unless you are adding hidden assumptions. It is easily shown in the case of some bureaucracies that a person will have a hard time getting something out of them, even though no single person will claim to be the one stalling the request. From the outside, the bureaucracy behaves as if it has a different goal than the (stated) goal of each individual.
