We look back to what happened historically in 1954. when the North Vietnamese took over in North Vietnam. the Catholic Bishop of Danang estimated that at least 500.000 people in North Vietnam who had opposed the Communist takeover in the North were either murdered or starved to death in slave labor camps. I saw something of that when Mrs. Nixon and I were in there in 1956. when we visited refugee camps where over a million North Vietnamese fled from the Community tyranny to come to the South. If at this particular point. the Communist were to take over in South Vietnam. you can imagine what would happen to the hundreds of thousands of South Vietnamese who sided with their own government and with the United States against the Communists. It would be a blood bath that would stain the hands of the United States for time immemorial.
