CHAPTER 7
Tactics

A strategic move is one that influences another’s choice in a way favorable to oneself by affecting the other’s expectations about how you will behave. Strategies are plans that require implementation. The strategies of commitments, threats, promises, and warnings need to be executed in ways that make them useful. This chapter looks at tactics used for making strategies effective, both personal strategies and those Schelling advocated during the Cold War that remain politically relevant.

would have the latest news about the outcome of the battle of Waterloo.
