Suppression of terrorist crimes in the contemporary battles of the Islamic State of Iraq and Syria (ISIS)

With the increase in committing terrorist crimes, governments in the international community have realized the importance of its global suppression. This is despite the fact that governments' support of terrorist groups in all phases of establishment or activity is the most fundamental component that has caused the deterioration of the effective international cooperation system in facing terrorist crimes. This is confirmed by the terrorist crimes of the ISIS group, whose threatening nature for international peace and security originates from the principle of terrorism as a threat to international peace and security. The United Nations, with its mechanisms, can play an effective role in the fight against terrorism. But, because of the non-cooperation of some member countries and the overt and hidden support of terrorist groups by a number of members, this organization has not achieved much success in fighting against terrorist groups. Therefore, although the terrorist crimes committed by ISIS are clearly stipulated in Articles 5 to 9 of the Rome Statute, but the International Criminal Court has not been able to deal with ISIS terrorist crimes due to the emergence of passive behavior at the global level. So, this issue should be addressed at the internal levels of the governments that involved in the armed battles of ISIS and in their territory by the subject of criminal proceedings.
