"The Viet Cong attacked all these weak points against the USA in the early 1970's and one can argue, successfully." The USA lost badly to both Korea and Vietnam. The Korean War was either a Roosevelt Invasion or President Truman (as common History books tell you.) And Vietnam was as bad. President Kennedy has no responsibility for Vietnam like implied in The Post and is one of the best presidents in USA History. When you hold a handgun or Military-grade gun, do not get pride I am a Master until you demonstrate it. But instead get pride in your Country's Gallantry.
