Oh the insanity.
Fighting ISIS on the ground will not make them go away. ISIS will simply return to being the guerrilla insurgency it was before last year. Meanwhile the lone wolf terrorism in the West will continue unabated. What it will do is drive more civilians in these areas into the arms of ISIS, like it did the first time. ISIS wants another 'crusade', don't give it to them.
The US has to support the local government's efforts, not get anymore involved themselves.
I remember in 2006 when Israel invaded Lebanon in an effort to wipe out Hezbollah. It was an unmitigated failure; while they dominated militarily, Hezbollah survived and rebuilt almost immediately. I guess 57% don't remember that.
