Second, the world's news media are responsible for this perception of America. Almost every major news medium on earth is either center-left or left. And the left around the world loathes America.
That the poll's results are synonymous with the left's perception of America is also shown by another result of the poll:
"A plurality of people polled in several officially American-allied nations also rated the United States as dangerous. Thirty-seven percent of Mexicans and 17 percent of Canadians view their neighboring country with suspicion on the world stage. A surprising 13 percent of American respondents rated their own nation the biggest threat to world peace as well."
Who are these Mexicans, Canadians and Americans? They are leftist Mexicans, leftist Canadians and leftist Americans.
Third, there is a morally flawed understanding of "peace." In much of the world (again, thanks to the left), peace has been so narrowly defined as to be morally irrelevant. It essentially means not having troops fighting in a foreign country. Thus, because the United States has troops fighting in Afghanistan and recently had troops fighting in Iraq, it is considered a "threat to peace." But Iran, with no troops on foreign soil, is not considered a threat to peace, even though it sustains terror movements, murders its own people, seeks to annihilate Israel, props up the mass murdering Syrian regime and is rapidly developing a nuclear weapon.
It is only according to this definition of "peace" that states like Iran, North Korea and China -- states that stay in power through violence -- are not deemed threats to peace.
Finally, here are two questions that should make clear the moral absurdity of the poll's results:
Would the world be more or less peaceful if only America disarmed?
Would the world be more or less peaceful if only America were armed?
