That may be so, or it may be false.
I don't think its impossible that the testing and subsequent drugs used to treat AIDS caused the number of deaths to spike.
I also don't think its impossible that HIV is causing AIDS.
I do think there are some very interesting, and unanswered questions, surrounding the issue. If the root of the issues is whether or not the HIV virus actually kills white blood cells, then that should be easy enough to prove.
