The Islamic State, proclaimed on 29 June 2014, has tremendously shaken up the Middle East and the whole world forcing hostile and friendly states alike to close ranks and create a collective military platform to fight and contain this new danger before it spirals out of control. This analysis probes the threats and the challenges the Islamic State, which has conquered and currently controls vast swathes across the Iraq-Syria borders, poses to the West and its Middle Eastern allies and examines why the challenges warranted a military response spearheaded by the US. It argues that the Islamic State poses formidable ideational challenges to the West, beyond its military threats to the Middle Eastern states, that question the very base and organizing principles of Western political order and the West’s dominance over the Middle East, what is better dubbed ‘Eurocentrism’ – a concept that articulates and sustains Western claim to universalism. Unless coerced into submission or at least militarily weakened, the IS holds the potential to successfully challenge eurocentric ideas with its own version of Islamic universalism.
