Only 11 percent of Americans had a favourable opinion of North Korea, an annual Gallup poll released on Wednesday found. (Agencies)
The survey came after a year in which North Korea's young leader Kim Jong-Un defiantly tested a third nuclear weapon, threatened to attack United States and executed his uncle and onetime mentor.
The poll of 1,023 Americans was taken from February 6-9, days before a landmark UN inquiry accused the totalitarian state of crimes against humanity.
Iran was not much higher at 12 percent. Iran has had tense relations with United States since the 1979 Islamic revolution overthrew the Western-oriented shah but the two countries have taken small steps to improve ties since President Hassan Rouhani swept to power in June elections.
Canada was once again the most popular foreign country for Americans, with 93 percent seeing the northern neighbour favourably.
The biggest drop was for Russia, whose favorability rating fell 10 points to 34 percent. Russian President Vladimir Putin has come under growing US criticism on issues ranging from gay rights to Ukraine's political crisis.
In other changes, India's favorability rating went up four points to 72 percent despite a showdown with United States over a diplomat's arrest in New York. Mexico posted the steepest rise, jumping 11 points to 58 percent.
