Explanation:
To explain why President Lyndon Baines Johnson lost public support in American involvement in the war in Vietnam, the correct answer is option C: due to. Let's break down the reasons:
1. Public opinion: The public's opinion turned against the war in Vietnam due to various factors such as the high number of casualties, the lack of progress in achieving victory, and the growing anti-war movement.
2. Casualties: The increasing number of American casualties in Vietnam caused public outrage and led to a decline in support for the war. The war became increasingly unpopular as the death toll rose.
3. Media coverage: The media played a crucial role in shaping public opinion about the war. Journalists reported on the grim reality of the conflict, including the devastation caused by bombings and the atrocities committed by both sides. This coverage contributed to the erosion of public support for the war.
4. Protests and anti-war movement: The war in Vietnam sparked significant protests across the United States. Students, activists, and other groups organized demonstrations, marches, and rallies, demanding an end to American involvement in the conflict. These protests further influenced public opinion and reduced support for the war.
5. Policies and strategies: President Johnson's handling of the war, including his escalation of troop levels and the implementation of controversial policies such as the Gulf of Tonkin Resolution, also contributed to the loss of public support. Many Americans questioned the effectiveness and justification of these actions.
In summary, President Lyndon Baines Johnson lost public support due to a combination of factors, including casualties, media coverage, protests, and the perceived ineffectiveness of his policies. These factors ultimately led to a decline in public support for American involvement in the war in Vietnam.
