it wasn't the influence of elite, Ivy League, specialists in Operations Research that got us into Vietnam...as my previous link shows, it was our concern for communist expansion...a geo-political calculus, not the operational efficiency (cough) those "Kids" sought to add.
How again did we get so far off from McKinsey and CNN+?...oh, I know...Curly's misinformed tangent to Vietnam...my bad for following that deflection.
