This chapter examines the capacities of the Arab League to effect security for its member states and their citizens, considering the League's constitution and its military assets, and also noting how its individual member states have reacted to the rise of ISIL. It outlines how the League and its individual states have acted over the problem of the rise of ISIL. An indicator of the Arab League's declared capacities is its constitution, the Charter of the Arab League, sometimes referred to as the Pact of the League of Arab States (LAS). The Arab Charter on Human Rights reaffirms the principles of the Charter of the United Nations, the Universal Declaration of Human Rights, the provisions of the International Covenant on Civil and Political Rights, and the International Covenant on Economic, Social and Cultural Rights. There is some evidence that the League has tried to act in accordance with the principles of R2P with regard to the Syrian civil war.
