The jihadist group known as Islamic Caliphate, which already controls vast area of Syria and Iraq, and is a threat to the neighboring Arab countries has recently proclaimed the restoration of the Islamic Caliphate. The proclamation of a “new system” coming to the contemporary world would only seem vague, if the Islamic Caliphate which now simply calls itself Islamic State (al-dawla al-islamiyya), The sudden emergence of a Caliphate that was so drenched in blood had the world, in the words of one journalist, wondering: ‘Where did these hell hounds come from?. The emergence of the “Caliphate” – an “Islamic State” and the alleged criminal actions associated with this emergence raise a number of important issues in international law, namely: the concept of a state, recognition, the concept of a failed state, the Articles of State Responsibility, cultural property, international humanitarian law including the issue of humanitarian intervention, and the responsibility to protect, and the use of force. More importantly, these events raise the question of the purpose of international law “what is it good for” in the one hand, and what is the Jordanian putative policy in the other hand.
