Describe how repeated iterations affect the political theory called the "prisoner's dilemma".

The prisoner's dilemma is a political game theory in which two participants are faced with two options, presented to each party separately. In the traditional prisoner's situation, the options are to rat on your counterpart in exchange for a deal or maintain your silence. If both parties rat, then there is no deal and both prisoners serve the max amount of time. If both parties maintain their silence, they both walk. If one party is silent while the other rats, the silent party receives the max and the ratting party gets a break. By having multiple iterations, political scientists have theorized that parties are less likely to make choices that are less advantageous to both parties.
