If our "leaders" or anyone really wants to cure Aids in Africa, hang 'em. HIV, talk about a great white hope.
Hell, with our own homelands sinking under a brown tide, maybe it's destiny that another continent empties out for us. Be bizarre if the races essentially reverse the positions of their homelans latitudinally won't it?
Of course, as soon as whites turned Africa into a paradise, and everybody else turns N. America and Europe into hellholes (provided they can even survive one winter), there will be a Jared Diamond-type historian popping up to say, no folks, race has nothing to do with it, it was only the luck of LOCATION that made some people develop and civillization and some people not get beyond the pointy-stick level for 100,000 years.
