Yes of course, the contention begins with whether you believe these groups would exist as they do if we didn't continue to do what we do and allow Israel to behave the way they do (and also, if you believe that any of the scary mooslems have a right to fight back against Israeli aggression). Placing the blame for these group's activities entirely on Iran is straight up pussy shit, and just another symptom of the American allergy to accountability for its own actions. We see it all around the globe, not just in the Middle East.
Sure, you're not wrong that the world would be better off if Iran's ability to export chaos was neutered, but approaching it from that direction is just kicking the can down the road. Groups like these will continue to pop up and gain power in perpetuity as long as we/Israel continue to be a destabilizing force in the region, and Iran is hardly the only willing sponsor out there. If not them, it will be someone else.
