Some speculate that a leader can tie their hands to follow through on a commitment to go to war if the leader is mad, as mad leaders might be willing to go to war even if the costs are catastrophically high. Also, sane leaders might try to bluff that their hands are tied by pretending to be mad. The chapter demonstrates that due to selection effects this kind of mad leader does not come to power, and that though leaders sometimes bluff that they are mad, this tactic does not work and does not tie hands. The chapter also evaluates the proposed tactic of tying hands by giving a computer the logistical ability to follow through on a commitment to go to war, independently of human decision-making. The chapter explains why states are deeply averse to taking this step, and demonstrates that no state has done this, including the alleged example of the Soviet/Russian Perimeter (or, “Dead Hand”) system.
