That is one additional thing that case study illustrates. The end result was far from the "status quo", though... it was an outright win for the North Vietnamese because they had destroyed our CoG (our will to continue fighting). They didn't attack our will to continue fighting by invading our will to fight somehow, did they? Did they blow our will to fight up with explosives somehow? Or did they send a regiment to burn the white house down that I never heard about?The Vietnamese case study illustrates that were were forbidden by political leadership to take the fight to the Viet Cong in their safe havens in Laos, Cambodia, and China. And that made the war unwinnable for us because we couldn't strike their COG. The end result was the status quo, minus tens of thousands of people killed.
Regardless, we're off topic.
