A crucial principle he employs in this argument, however, also implies the pointless retaliation after a failed threat could also be rational. In this paper, I introduce one possible reformulation of the Cooperation Argument, by replacing its second premise with a principle connecting rationally adopted intentions, rational action, and rational reconsideration, and a specific theory of rational reconsideration. I then argue that this reformulated Cooperation Argument is not susceptible to any form of the Deterrence Objection, and conclude that the Deterrence Objection may be circumvented if proper attention is paid to the role of rational reconsideration.
