Agree that "useless" was a bit harsh. Perhaps "unachievable"?
It's a bit like dieting. You take someone who has been chubby their entire life, put them through a bootcamp, and then look at their weight 5 years later. The stats are not looking good in those cases, and I think they largely reflect our efforts in up-leveling the political landscape in historically corrupt countries.
I am not saying that we shouldn't keep trying. But I think we should internalize that the chances of success are slim, and then make that a part of our upfront decisioning process on budget, casualties, political cost, etc.
