Libya was doing very well before it was invaded. The leader was repressive, but they had tremendous oil wealth. They clearly cared about giving this wealth back to their people, evidenced by the free education, healthcare, and lump sums of money to married couples etc. I find it more likely that the government of Libya would have been willing to invest in the protection of it's people by repairing the dam regularly, versus any western country that only wants to extract maximum profit from it's inhabitants by charging for all services and privatisation of previously national services, all while the leaders pocket hundreds of millions (the UK, for example).
