Most of the arguments that we were betrayed in Vietnam are based on the idea that Vietnamization worked and that all we needed to do was to provide funding and bombing runs to keep South Vietnam viable.
Proving that he in insane, Norman Podhoretz appears to imply in his latest bromide that Nixon should have kept U.S. ground troops there en masse:
In 1972, Richard Nixon was elected by landslide to a second term as president, but in campaigning against George McGovern's call for us to withdraw from Vietnam, Nixon did not sound an opposing call to fight on to victory. On the contrary: He too promised to get us out of Vietnam. The difference was that he also promised to accomplish this with our honor intact.
In other words, we should have kept fighting on the ground. I suppose that Podhoretz is disappointed that we didn't keep up the 1968 level of casualties throughout the 1970s.
That is all.
