Some fun crosstabs too. E.g., in all of the Western countries I looked at, men were more likely than women to view Iran and North Korea as a threat to world peace, whereas women were more likely than men to name Afghanistan and Iraq.
In China, it was the least educated people who tended to view the US more as a threat, whereas in Western countries it’s the more educated people who are more likely to name the US. Also, the age gap on the US is such that in both China and Russia, people over 65 are most likely to view the US as a threat, whereas it’s more young people who say that in Western countries.
In fact, in the US itself, in the 18-24 subsample, the results are:
USA 22%
Afghanistan 15%
North Korea 13%
So a plurality of young people in the US say that the US is the biggest threat to world peace.
