Suppressing them didn't cause them to stop fighting, though. In every guerrilla war the conventional army is nominally in charge, and generally never loses any sort of pitched battle. The whole military theory of guerilla warfare is to avoid shootouts in favor of hitting the enemy and running away.
You're admitting you're wrong? You're now agreeing that the US army could suppress an insurrection indefinitely and could only be stopped by a split within the military itself. A scenario that has nothing in common with what happened in Afghanistan.
