Population Program Affects on National Stability -- A Question

Over the last couple of weeks the television has shown riots in Pakistan after the assassination of Bhutto and in Kenya after the elections. Last night I was Charlie Wilson's War (which is a very good movie) which showed crowds of Afghanis celebrating the speech of Chairman Doc Long's pledge of U.S. support for their anti-Soviet insurgency. In all that footage what seems most evident is the fact that it is young men who are doing the rioting. Indeed, all those young men seem to be poor.

In all these countries the rates of population growth are are very high, and there are lots of young men. Indeed, the ratio of young men to older people is high. We know that effective population policies also involve the education and empowerment of women. And there is a lot of information that slowing the rate of population growth can lead to more investment in the kids who are born, and thus to higher rates of growth of per capita income.

Is it perhaps the case that good population policies produce a generation later more peaceful societies?
