Very interesting charts. I am surprised at the low support for ISIS among the countries cited. By the way, do you have a link for these charts?
Don't get fooled by the numbers. Most of those who said "Don't know", and many of those who said that they don't support ISIS are secret Islamic State sympathizers. The survey was conducted by a Western agency, and I am sure that some of the respondents hid their jihadi sympathies from the survey-takers. And here is the link:
