After two global conflicts, we have seen a long period of apparent peace. However, behind the fragile stability, massive forces were moving. Major international factors, such as globalization, the increase in the world population, the lack of raw materials, and the formation of international factions, have weakened pluralism in favor of an increasing polarization on the international stage. In today's world, some major regional powers are competing for global dominance.

In Defcon, internal frictions push decision-makers to seek international success in order to establish their power, even if it means conflicting with international competitors. In an atmosphere of increasing tension, the major powers embark on an arms race to prepare for a global-scale conflict. Whoever controls the hegemonic superpower at the end of the fifth round wins, and to achieve this, that player must take the highest position in the consensus index, which consists of two distinct rankings: the reputation index and the military index. Those who find the right balance between military power and public support will win the game.
