How does the concept of the Prisoner's Dilemma manifest in strategic board games like Diplomacy?

The Prisoner's Dilemma is a classic example of game theory, highlighting the conflict between individual and collective interests. In board games like Diplomacy, players must navigate trust, betrayal, and negotiation to achieve their objectives. This often involves decisions that mirror the Prisoner's Dilemma, where cooperation might lead to mutual benefits, but self-interest can yield individual advantage at the cost of mutual trust. Understanding how such scenarios unfold within these games can provide deeper insights into human behavior and strategic thinking. How do different players approach these dilemmas, and what strategies tend to be most successful in a board game context that mirrors real-life strategic conflicts?
