Nash only came up with a theory/framework, not the ‘idea’ itself. It’s simple enough for anyone to understand. But Somalis are quite revolutionary as they came up with and practice ‘lose/lose’ wherein you destroy yourself in order to destroy everyone elseI'm a win win type of guy, I think that provides more benefits over a longer time period for Somalis, win and lose is short term gain type of thinking, zero sum doesn't last to long before the other side wakes up to it. Ironically the culture there is win and lose, which can explain the stalemate 30 years. John Nash brilliant win win and shared losses ideas was very much revolutionary in business and politics and military fields.
That means everyone has to share a loss somewhere across all clans for it to work, if they don't even believe in the theory and prefer zero sum, show them it just extends the 30 year stalemate to 100 years, if that doesnt wake them up, just know their chasing a fantasy.
