Syrian Refugee Flows: Security Risks and Counterterrorism Challenges, Preliminary Findings of a House Homeland Security Committee Review [open pdf - 78KB]
From the Summary: "More than four million Syrians have fled the conflict zone in their home country, contributing to the largest global refugee crisis since World War II. According to statistics from the United Nations High Commissioner for Refugees, more than half a million of them have traveled to Europe to seek asylum or are attempting to resettle elsewhere in the West, including the United States. In response to the crisis, the Obama Administration has announced plans to 'surge' admissions of Syrian refugees into the United States, including admitting at least 10,000 over the course of this fiscal year. A review by the Majority Staff of the House Homeland Security Committee concludes that the Administration's proposal will have a limited impact on alleviating the overall crisis but could have serious ramifications for U.S. homeland security. Additionally, widespread security gaps across Europe are increasing the terrorism risk to our allies and present long-term implications for the U.S. homeland."
