AIDS treatment in particular has not only saved lives—saved mothers to raise their children and teachers and nurses to serve their communities—it has also encouraged testing and decreased stigma. An infectious disease becomes less terrifying and more manageable when it is not a death sentence. Not all American foreign assistance is effective.

National scale-ups and countrywide plans encourage real development, because they require the creation of supply, management, and human resource systems—the kind of accountability and transparency that can benefit an entire health system and society.
We have learned that, like an effective military, effective ...
