or join a public demonstration about something?" Positive responses were quite low; not many people wanted to protest anything, and those who did want to show a public demonstration often wanted to demonstrate in support of the Vietnam War. However, when the American Public was asked in 1990, "Looking back, do you wish that you had made a stronger effort to protest or demonstrate against the Vietnam War, or not", 25 percent said they wished they had. A major factor in the American public's disapproval of the Vietnam War came from the casualties being inflicted on US forces. In a Harris poll from 1967 asking what aspect most troubled people most about the Vietnam war the plurality answer of 31% was "the loss of our young men." A separate 1967 Harris poll asked the American public how the war affected their family, job or financial life. The majority of respondents, 55%, said that it had had no effect on their lives. Of the 45% who indicated the war had affected their lives, 32% listed inflation as the most important factor, while 25% listed casualties inflicted. As the war continued, the public became much more opposed to the war, seeing that it was not ending. In a poll from December 1967, 71% of the public believed the war would not be settled in 1968. A year later the same question was asked and 55% of people did not think the war would be settled in 1969. When the American public was asked about the Vietnam-era Anti-War movement in the 1990s, 39% of the public said they approved, while 39% said they disapproved. The last 22% were unsure. General effects The opposition to the United States' involvement in the Vietnam War had many effects, which arguably led to the eventual end of the involvement of the United States. Howard Zinn, a controversial historian, states in his book A People's History of the United States that, "in the course of the war, there developed in the United States the greatest antiwar movement the nation had ever experienced, a movement that played a critical role in bringing the war to an end." An alternative point of view is expressed by Michael Lind. Citing public polling data on protests during the war he claimed that: "The American public turned against the Vietnam War not because it was persuaded by the radical and liberal left that
