Yes but look at it this way. Many of the radical Muslims died for Allah in Iraq. And the young people in Iran are (relatively) liberal. It’s only a matter of time before everyone behind the ‘79 Revolution would die. Once that happens, Iran will become one of the most free and secular countries in the Middle East, almost like Turkey although they’re becoming more Islamist recently.
Correct on the latter, not so on the first.
Poverty and lack of education where the Koran is the only thing taught provides a tool always offering a steady stream of recruits.
Look up the story on the shootings in India last year. The culprits were recruited from impoverished backgrounds. They are easily led and feel they have no future. Perfect cannon fodder.
