You will never catch up with the spread of AIDS no matter how much money, no matter how many antiretrovirals are put into the system, unless you stop its growth. And the only way to stop its growth is prevention.
I think history is continuous. It doesn't begin or end on Pearl Harbor Day or the day Lyndon Johnson withdraws from the presidency or on 9/11. You have to learn from the past but not be imprisoned by it. You need to take counsel of history but never be imprisoned by it.
