Players in game theory often benefit from cooperating, but the game structure can lead to defection. Only in zero-sum games do players have no incentive to cooperate. States, like individuals, are self-interested and may strengthen refugee protection for their own gain. The EU uses initiatives like the European Refugee Fund to promote cooperation among Member States. European countries rely on immigration for their economies, leading to a "need-based selection process" rather than a zero-immigration policy.
