Michael Bayer is a former chief of the Department of State's (DOS) transnational criminal investigative office. Bayer's book addresses the ques- tion of how the United States can engage international partners more effectively to address worldwide manifestations of destabilizing violence, often indiscriminately labeled "terrorism." Bayer researched and wrote this book while participating in the Research Fellows Program under the Center for Strategic Intelligence Research (CSIR) at the National Defense Intelligence College (NDIC), Washington, DC. He received much support and assistance from two CSIR editors, Dr. William Spracher and Dr. Russell Swenson. The goal of the NDIC Press is to publish high-quality, valuable, and timely books on topics of concern to the Intelligence Community and the U.S. government. Books published by NDIC Press undergo peer review by senior officials in the U.S. government as well as from civilian academic or business communities. The views expressed in this publication are those of the author and do not necessarily reflect the official policy or position of the Defense Intelligence Agency, the Department of Defense, or any other U.S. government organization. Clearance by the public affairs offices of DIA and DOS does not imply endorsement of factual accuracy or opinion. Authors of NDIC Press publications enjoy full academic freedom, provided they do not disclose classified information, jeopardize operational security, or misrepresent official U.S. policy. Such academic freedom empowers them to offer new and some- times controversial perspectives in the interest of furthering debate on key issues.
