What about the recruitment from the West though, like those foreigners who leave america,canada or europe to join them on their own free will. They can't be that stupid cause shabaab has alot of foreign fighters same did ISISYou are not wrong either.
My point is that any reasonably educated person can read the Quran and understand that each verse or chapter was written in a specific context.
For someone to not understand that, then their problem does not lie with the scripture but rather their lack of education, either in a religious sense or academic sense.
