When one thinks of traditional weapons of war, it is not common that dams or rivers are the first to come to our mind. The idea of water being a weapon of war might at first seem absurd, as it is not a weapon in the traditional sense. However, water can and has been used successfully as a weapon of war, as will be discussed in this report detailing the strategy employed by ISIS in its quest for a Sunni-Islamic State in the Middle East. ISIS, known by many names (Islamic State, ISIL, Daesh, Islamic State Organization), is a Salafi-militant group operating within their selfcreated "caliphate" which exists in the states of Iraq and Syria. They began to make a serious bid for power in the summer of 2014 and successfully utilized water as a weapon with which to leverage themselves militarily and as a method of social outreach to gain support in two countries whose water infrastructures have been heavily damaged by years of conflict. This strategy has been, in the writers opinion, the key to their success. They have utilized one of the regions most precious resources in a multi-faceted strategy to build a state that will endure in a region divided by sectarian and ethnic conflicts.
