Most countries consider ISIS as one of the most dangerous terrorist organization in which operation has brought a major threat to national security and peace in many countries, as well to human, regional and global security and peace because of its ability to amass combatants, funding, and territory. In achieving its goals to establish a fundamentalist Islamic state as well as to impose its worldwide view of Islam extremism, it practices political and military tactics by the use of ruthless force on both Muslims and non-Muslims people. Ethnic cleansing carried out by ISIS towards Non-Muslims can be considered a very serious crime and represents a part of terrorist actions which aims to force the scenario of dividing Iraq and creating a terrorist front in its occupied territories in Iraq. The rapid advance of ISIS in Iraq has completely changed the balance of power in the country. In addition, it threatens not only the integrity of the country, but also leads to redrawing of borders across wider regions.
