This thread is a spinoff of the Dr. Phil discussion. Ref. whether or not the war in VietNam was a military success, I think we could craft a very simple formula. 1) establish what the military objective of the war was; and 2) a yes/no answer to the question of whether we achieved it. IMO, the military objective of the war was something along the lines of, "prevent the military takeover of South VietNam by the regular and irregular forces of North VietNam." If that is the case, then we failed to achieve that military objective.
