Strategypage looks at Afghanistan.
The place is a failed state--or perhaps more accurately a never-was-a-state--for a number of reasons.
Islam cripples the geographic location as it does in other places because it is a unified theory of religion-state; and a violent fanatical minority likes it that way and will kill to achieve it--or at least stop any other method, like democracy and rule of law.
Iran and Pakistan find a weaker Afghanistan useful.
And peace talks are really just another way that the Taliban are trying to win--which the talks hopefully expose so more people will oppose the Taliban.
Do read it all. And have a super sparkly day.
