Jeffrey Sachs is professor and director of the Center for Sustainable Development at Columbia University. He’s a leading intellectual on global economic affairs in general and sustainable development in particular. Here he chooses the unusual way of communicating: Instead of going into a lot of “academic” issues and dimensions of the US-led war on Afghanistan since 2001, he characterises the underlying mentality, decision quality and level of knowledge by using the word “stupidity” a number of times. And that’s what this US policy has been: stupid. Repeatedly stupid. We find it important that people proven excellent intellectuals do not feel that they have to separate the personal and academia and feel free to express themselves in plain language – indicating also, of course, a sense of frustration and anger over that very ignorance . . . stupidity and its tragic human consequences. Perhaps that style of communication stands a better chance to make people wake up?
