South Korea
A 2021 Morning Consult poll found that 39% of South Koreans held an unfavorable view of the U.S. Although the majority of South Koreans support the American alliance, Katharine Moon noted that "anti-Americanism also represents the collective venting of accumulated grievances that in many instances have lain hidden for decades."
Belgium
The U.S. and Belgium have maintained a primarily friendly relationship for over 176 years. However, according to a 2012 poll, only 26% of Belgians approve of U.S. leadership. Belgium works closely with the U.S. to encourage economic and political cooperation, having welcomed hundreds of U.S. firms into its country.
