We're not fighting WWII. This is an entirely different situation.
The current tactics did not work in Nam and won’t work here.
We didn't use these tactics in Vietnam. We killed two million Vietnamese and still lost. The Russians did something similar to that in Afghanistan and lost.
Maybe the top generals learned something from Vietnam and know more about counterinsurgency warfare than anyone on this thread.
We lost Vietnam by restricting what our troops can do. We are doing the same STUPID tactic in Afghanistan!
