The mistake was in becoming an occupying force.
No offense, but speaking for one of the guys in uniform, he'd prefer not to go back to the cluster****. Very little has been accomplished by their bravery, and that's a shame. But the shame belongs to those who put them there, not the guys and gals themselves. I'm pretty sure that 99.9% of all Americans understand this. It's not rocket science.
I'm appalled that you would even try to lay shame at the feet of our military personnel. Seriously. What are you thinking? It's not their fault that they were sent in without a plan as to how this nation building would occur.
