In September 2014, US President Barack Obama announced a “comprehensive strategy” to degrade and destroy ISIL. Obama stated, “I will not hesitate to take action against ISIL in Syria, as well as Iraq.  This is a core principle of my presidency:  If you threaten America, you will find no safe haven.” But despite this announcement, questions over the nature, goals, and instruments of US policy towards ISIL still continue to be asked in the context of a debate between those who think that the US is not doing enough to take on ISIL and those who think it would be better for the US not to expand its military involvement in the conflict. This debate has been influenced by internal American political polarizations in the form of the critical position taken by leading Republicans such as Senators John McCain and Lindsey Graham, who view the Obama policy as weak, and Middle Eastern regional rivalries over the position towards ISIL and the nature of the political choices that must frame the confrontation with it.
