I don't recall stating that Congress was preventing anything. I said politics is. Portraying ourselves as the "good guys" and "winning the hearts and minds" doesn't really include hunter-killer teams of Green Berets, Marine Recon, and/or Navy Seals running clandestine operations with impunity in the countryside.
What I'm talking about is a conventional, standing army in a guerilla war is nothing more than a target. The most successful counter-insurgency in Vietnam was conducted by the Marines. They lived with the villagers in small teams. They shared their lives, dangers, all that good stuff, and were far more accepted than a reinforced rifle company kicking everyone out of the village and torching because they suspected the VC were there.
And I am NOT trying to rehash the Vietnam War, just present an example fo something that worked, but was ignored by the beancounters.
