Quite a lot is being done actually. There are often arrests made after violent acts or before it if the authorities receive credible intelligence in time. In communities work is done especially with the male youth in a effort to curb fundamentalism. Many Imams give sermons about about the dangers of extremeism.

I read a lot about this in Arabic press - newspapers, internet.

And I would say the world is most definitely paying attention to fanaticism and extremeism. Many countries policies and procedures have been updated. Intelligence sharing has increased. I see a global effort. Everyone should and can play a part. There are organisations one can join online to promote human rights, peace,etc.
