The argument that if you keep it clean, everything is fine, doesn't really work in the real world. You are most likely to get HIV a few hours after sex. The foreskin harbours the virus, and then it enters the bloodstream. If you have no foreskin, the virus has no place to stay. Unless you are going to thoroughly wash yourself directly after unprotected sex, every single time, then you're better of being circumcised.
And yes, condoms are obviously much more effectively in reducing any infection, but men don't always use condoms, especially in developing countries where sex is more for procreation and less for pleasure.
