Major Anderson provides an excellent overview of terrorist financ­ing and expands upon how it fits into the broader construct of threat financing. He articulates the significant challenges any government faces in trying to interrupt the terrorist networks use of the global financial system. The sheer immensity of this system provides ample opportunity for terrorists to operate undetected or unhindered. He also highlights that the very international nature of the global eco­nomic system presents enormous challenges in trying to coordinate amongst the almost 200 sovereign states that comprise the current world order.
