Why Trump’s madman strategy failed — Professor Han Soon-goo (Department of Economics, Yonsei University)

When beliefs about execution matter more than the size of a threat
In a hypothetical commercial negotiation, accepting a demand costs 4 for certain, while refusing produces a loss of 20 with probability p if the other party stops trading. Under risk neutrality and with no other effects, refusal has expected cost 20p: 2 at p=10% and 6 at p=30%. In this simple model, concession costs less when 20p>4, or p>20%. With the same potential loss, a different belief about execution can change the choice. The values of p are not measured probabilities; repeated behavior, execution costs and alternative partners can change both beliefs and losses.
Check for yourself
- What is actually lost after refusal, and what can be recovered through another trading partner?
- What costs does the other party bear by carrying out the threat?
- How do past retreats and contractual constraints change beliefs about execution?
Limits of application
This does not estimate any country’s or leader’s behavior probability or optimal diplomacy. It assumes risk neutrality, a single loss and a certain concession cost, excluding reputation, long-term cooperation, cascading retaliation, legal rights and nonfinancial values. It does not recommend increasing uncertainty or making unconditional concessions.
- What to look for
- Understand how relationship-specific investment and fewer alternatives change bargaining power, and how repeated threats alter credibility.
- Why it matters
- Assess alternatives, contracts, execution costs and beliefs instead of explaining bargaining through closeness or power alone, while separating historical analogy from verified fact.
Timeline
8 segmentsThe madman strategy is explained as inducing concessions by making an opponent believe even costly actions may actually be carried out. Repeated retreats may weaken threats by changing beliefs, but do not establish that unpredictable leaders are always superior or that current negotiations have empirically failed. Assessments of Trump’s behavior and failure are the speaker’s interpretation; actual bargaining also depends on capability, costs, domestic constraints, reputation, outside options and losses from miscalculation.
