A very comprehensive survey and detailed analysis of American public opinion concerning foreign policy issues. There is a link to the full report.
“Indeed, the most striking finding of the 2014
Chicago Council Survey is the essential stability of
American attitudes toward international engagement,
which have not changed all that much since the
Council conducted its first public opinion survey 40
years ago. As they have for four decades, Americans
support strong US international leadership, place primacy
on protecting American jobs over other foreign
policy goals, favor diplomacy with countries that are
hostile toward the United States, support participation
in many international treaties and agreements, and
endorse trade despite economic setbacks. Americans
remain selective about when they will support putting
US troops in harm’s way, but are most likely to do so in
response to top threats or humanitarian crises.”
