|The Nash Equilibrium
In game theory, Nash equilibrium [named after John Forbes Nash, who proposed it] is a solution concept of a game involving two or more players, in which each player is assumed to know the equilibrium strategies of the other players, and no player has anything to gain by changing only his or her own strategy unilaterally.
Projected Equivalence (An Expansion of the Nash Equilibrium)
In a counter terrorism, general war and total war scenario, failures to obtain projected equivalence related benefits would make many nations vulnerable to attack or scenarios that have a projected equivalence of the same [threats or provocative actions that are coercive]. Hence, all nations need positive projected equivalence to secure, improve and sustain their quality of life as a nation state.
Social Diversity [classic and modern day ideological tolerance]
National Defense Viability [viability is distinctly different from capability]
Defense/Economy based Peripheral Benefits [Security creates sustainable alliances, treaties and income]
