When there are two objects to negotiate, the decision to negotiate them simultaneously or in separate forums or at separate times is by no means neutral to the outcome, particularly when there is a latent extortionate threat that can be exploited only if it can be attached to some more ordinary, legitimate, bargaining situation. The protection against extortion depends on refusal, unavailability, or inability, to negotiate. But if the object of the extortionate threat can be brought onto the agenda with the other topic, the latent threat becomes effective.

XREF: Connects to negotiation theory and the strategic use of agenda-setting, as in Thomas Schelling's work on commitment and bargaining.
