The international political system has a long track record of cajoling nations into joining treaties that theoretically are like this.
It's not prisoner's dilemma, because the main property of the PD problem is that parties are prevented from communicating and cooperating with each other. When there's negotiations, transparencency/monitoring, etc, parties can cooperate. If you think international treaty development is like PD, you are due for a for a big optimism update!
