Pakistan
Pakistan's disapproval rating of U.S. leadership was greater than all but 4 other countries surveyed. America's lasting military presence in the country after the 9/11 attacks led many Pakistani civilians to harbor unfavorable views of the country.

America and South Africa currently enjoy "cordial relations" despite "occasional strains," with 57% of South Africans viewing the U.S. favorably.
