Afghan Intelligence criticism

In this BBC report, U.S. top military intelligence officer Major General Michael T. Flynn is highly critical of our intelligence efforts in Afghanistan. I found the degree of candor surprising:

He says "the vast intelligence apparatus is unable to answer fundamental questions about the environment in which US and allied forces operate and the people they seek to persuade. Ignorant of local economics and landowners, hazy about who the powerbrokers are and how they might be influenced, incurious about the correlations between various development projects and the levels of cooperation among villagers, and disengaged from people in the best position to find answers".
