Not so, as said before Turkey and/or the Saudis could also eliminate this threat the the emotional well-being of the west:)
It could also be done with a single US Infantry division and associated logistics/air support.
The ONLY reason these guys are not dead or hiding in a hole right now is because no organized force has taken them on.
They are simply street thugs, noting more.
“Not so, as said before Turkey and/or the Saudis could also eliminate this threat the the emotional well-being of the west:)” — before i go, you’re correct, they could. The caveat, ones you mention would need incentive to do so. The wellbeing of the west isn’t one incentive. Keeping AQ et al running are in their best interest.
