 We know the AIDS epidemic won't end with the treatment options we have now. It will only end when we stop new infections and no one dies before their time. There are too many places where the main source is injection drug abuse and there's no political constituency. So the first time there's a bump in the road, it's easy to cut them off and think it's their own fault. In spite of the fact that, as I said, I will say again, all the evidence is if you do substitution therapy and clean needles, drug use goes down, not up. So we need strategies that deal with the real issue. In Europe and Central Asia, the AIDS epidemic is driven primarily by intravenous drug use. We know what works, harm reduction. And our foundation, for example, works in Ukraine and we've helped to get methadone moving there. But nobody's done it to scale. And we can no longer say we need to let a thousand flowers bloom and pretend everything works as well as everything else. We've got evidence now and we don't have all the money in the world. We should find what works.
