The Chicago Council on Global Affairs 2015 Annual American Survey was conducted by The GfK Group (GfK, formerly Knowledge Networks) using a sample from KnowledgePanel.  The study examines the attitudes and perceptions of Americans across a range of U.S. and international public policy issues. Topics include possible threats to the U.S. interests, such as Islamic terrorism, Russian territorial ambitions, China’s economic power, and North Korea’s nuclear program; the government’s preparedness to handle these threats; foreign policy goals for the U.S.; confidence in the responsible leadership of specific nations; global economic issues, and the U.S. role in the world. Respondents are asked about the use of U.S. troops in a number of hypothetical conflicts. This survey of 2182 U.S. adults was conducted May 28-June 17, 2015.
