20) Scenario 17-3.
Consider two countries, Kinglandia and Rovinastan, that are engaged in an arms race.

weapons. Each country prefers to have more arms than the other because a large arsenal
gives it more influence in world affairs. But each country also prefers to live in a world
safe from the other country’s weapons. The following table shows the possible
outcomes for each decision combination. The numbers in each cell represent the
country’s ranking of the outcome (10 = best outcome, 1 = worst outcome).
