**Position: FALSE**

The claim that HIV definitively causes AIDS is misleading. While HIV is strongly associated with AIDS, the relationship isn't as straightforward as the claim suggests. For example, not everyone infected with HIV develops AIDS, and some people without HIV can develop AIDS through other means, like certain cancers or drug use. Additionally, the idea that treatment response "proves" causation ignores the complexity of immune system interactions. Natural experiments, like the case of the "Berlin patient," show that HIV can be controlled or even eradicated, but they don't definitively prove a direct causal link in all cases. More research is needed to fully understand the relationship between HIV and AIDS.
