Can you talk a bit more about situations where WHO or UNESCO have overridden a country's health system? As a US citizen I see WHO as 1) offering guidance and 2) funding programs in poorer countries' health systems.
UNESCO, well, I'm looking at its website and Wikipedia article now, and I don't understand what it does. (Or maybe it would be easier to list what it doesn't do, since even its list of sponsored institutions is mind-numbingly long.)
