A war crime is a violation of the rules of war and international humanitarian law. This crime has been committed in different countries and at various times, and many people have been victims of it. Afghanistan has not been safe from the damages of this crime because the previous wars in this country show that people have been negatively impacted. Afghanistan Fair Trial has investigated alleged crimes to provide justice in society. The present research is applied by purpose and has used a descriptive-analytical method. Data were gathered using the library method. The findings showed that the Government of Afghanistan has legal legitimacy after finding public legitimacy by holding two Loya Jirgas and two direct elections. However, it has not been able to provide justice, safety and rights due to the double standard(s) policy. The criminals of the main and dangerous crimes, which have negatively affected the international community as a whole, jeopardize peace, security and comfort. Thus, they should not be allowed to escape justice by misusing the power and safety they enjoy. To ensure this case does not occur, some measures have been taken to define war crimes and to determine punishments for violators, for example, The Hague Agreement, Treaty of Versailles, The United Nations War Crimes Commission (UNWCC), Nuremberg Trials, The Tokyo Trial, Rastatt international court of justice, The Universal Declaration of Human Rights (UDHR) and The International Covenant on Civil and Political Rights (ICCPR).
