Unfortunately, the data from Africa does not translate well. Those trials were of heterosexual men in countries where the virus is everywhere, education about safe sex is practically nonexistent, and condoms get in the way of the need to father children.
In the United States, the AIDS epidemic is very different. The highest risk groups are men having sex with men (whether openly or covertly or even forcibly — in prison rapes, for example), people who share needles and women who, often unknowingly, have sex with high-risk men. Although it has been killing people here for 25 years, AIDS has not turned into a generalized epidemic like it has in Africa. Sex education, condoms, abstinence, antiretroviral drugs and the fear of death have concentrated it mostly in small pockets of the population.
And for most of those people, circumcision probably won’t do much good.
