This article examines the political and legislative history of a formerly classified anti-terrorist finance program initiated in the days after 9/11 that subpoenaed millions of financial records from the Belgian-based <em>Society for Worldwide Interbank Financial Telecommunications</em> (SWIFT) without the knowledge of European authorities. The European outrage in response to its public disclosure in 2006 — and the subsequent struggle to generate support for the continuation of the program — has been interpreted by many as further evidence of a strategic divide concerning American and European efforts to thwart terrorism. This research will investigate the dramatic changes to the American anti-terrorist finance regime after 9/11, and will demonstrate that the European reluctance to cooperate with this program represents a fundamental disagreement concerning the prioritization of privacy rights rather than an unwillingness to take the steps necessary to combat the financing of terror.
