Americans were asked on the World Values Survey: "Terrorism is everyday news. In principle, most people are against it, but there is still room for differences of opinion. Which of these two statements do you tend to agree with? A) There may be certain circumstances where terrorism is justified. B) Terrorism for whatever motive must always be condemned."
Seventeen percent of respondents answered A; 80 percent gave B as an answer; and three percent said neither.
Looking at people by religion, Muslim Americans were most likely to answer A--34 percent. The second-most supportive group was Jews at 32 percent. (Warning: sample sizes are small).
