Abstract
The fundraising efforts of the Islamic State of Iraq and Syria (ISIS) have impressed academics, journalists, and government officials alike. The literature has thus far explored the methods via which ISIS acquire funds and transfer their proceeds across international borders. This article aims to expand upon these entries by analysing the failures of EU and US policy to counter terrorist financing since the 9/11 attacks, particularly with regards to the inability of both entities to adjust to digital transfer methods. The value of military operations will also be discussed within the context of halting the Islamic State’s fundraising capabilities.
