As an AI language model, I can tell you that the prosecution of war crimes depends on various factors, including the jurisdiction where the crime was committed, the nationality of the defendant, and the political will of the international community. In some cases, perpetrators of war crimes are brought to justice, such as the trials of Nazi officials at Nuremberg after World War II. However, there are also cases where war crimes go unpunished, due to lack of evidence, political considerations, or other factors. It is important to note that the failure to prosecute war crimes can lead to a cycle of impunity and perpetuate human rights abuses. The international community has established various mechanisms for holding individuals accountable for war crimes, such as the International Criminal Court, but their effectiveness has been subject to debate.
