"On September 10, 2014, President Obama announced the formation of a global coalition to 'degrade and ultimately defeat' the Islamic State (IS, aka the Islamic State of Iraq and the Levant, ISIL/ISIS or the Arabic acronym Daesh). Subsequently, some 60 nations and partner organizations agreed to participate, contributing either military forces or resources (or both) to the campaign. In Brussels in December 2014, these sixty partners agreed to organize themselves along five 'lines of effort,' (by contrast, the U.S. strategy involves nine lines of effort), with at least two countries in the lead for each:  Supporting military operations, capacity building, and training (led by the United States and Iraq);  Stopping the flow of foreign terrorist fighters (led by The Netherlands and Turkey);  Cutting off IS access to financing and funding (led by Italy, the Kingdom of Saudi Arabia and the United States);  Addressing associated humanitarian relief and crises (led by Germany and the United Arab Emirates); and  Exposing IS' true nature (led by the United Arab Emirates, the United Kingdom, and the United States)."
