The report, "Preventing War. Shaping Peace. Overkill: Reforming the Legal Basis for the U.S. War on Terror," by the International Crisis Group, focuses on the legal basis for the U.S. war on terror. The report discusses the Bush and Obama administrations' approaches to the war on terror, including the use of associated forces, institutionalization, and the counter-ISIS campaign. The report also examines the Trump administration's intensification and further expansion of the war on terror, including increased strikes and ground combat in Africa. The report concludes that the legal basis for the war on terror needs to be reformed to prevent overkill and to ensure that the war is conducted in a way that is consistent with international law.
