I got the first sentence of the paragraph and that was as far as I could get.
"the politics of getting more lifesaving antiretroviral medicine to the millions of HIV-infected people who need it in the developing world, especially in Africa."
That should be life prolonging, not life saving. Unless they are talking about the drugs that prevent HIV from transferring from the mother to the child, and there are some concerns about those drugs.
that emphasize abstinence over the trusted HIV-blocking method of using condoms.
So abstinence can't be trusted?
Mechai told The Associated Press. "How can you [Leaders] afford to let your people become sick and die in larger numbers than by so-called enemies in wars?"
Well actually they got the disease because of their personal choices (barring they did not get aids from poor health care). So the leaders did not "let" it happen, it happened because people made poor choices.
