In 2003, the Defense Intelligence Agency asked the NRC to form a standing committee to help develop study topics about technology warning. One issue that was identified was the growing dependence on foreign suppliers of critical technology as a result of the increase in globalization of economic activity. Two important questions emerged for study: what is the risk of denial of critical products from foreign sources and what must the United States do to assure access to future critical products and technologies? This report presents an assessment addressing those two questions. It also provides an analysis of a strategic approach to manage the consequences of this trend towards increased globalization. Finally, the report offers a set of recommendations to implement this strategy and to increase assurance of access to critical technologies.
