Nixon, 01/20/68: Former Vice President Richard Nixon speaks at a political rally in Houston. According to United Press International, the appearance drew a crowd of 1,500 supporters. In his speech, Nixon criticized President Lyndon B. Johnson's foreign policy approach, warning that the Soviet Union would match American nuclear capability within three years. "The only reason we have avoided a third world war," he said, "is because of our superior nuclear strength." The stop was part of a 16-hour tour of Texas, with Nixon speaking in San Antonio and Dallas before making his way to Houston. While Nixon had already decided to run for president by this time, he would not officially announce his candidacy until February 1.
