Final answer:
Americans who opposed the Vietnam War were often labeled 'doves' and included groups like the Vietnam Veterans Against the War. Opposition stemmed from moral objections, the draft, impacts on foreign civilians, and the diversion of resources from domestic issues. Despite initial support for the war by many Americans, opposition voices grew stronger over time.
Step-by-step explanation:
Americans who opposed the Vietnam War were often referred to as 'doves,' in contrast to 'hawks,' who supported the war effort. Opposition grew over the years, with movements such as the Vietnam Veterans Against the War (VVAW) gaining traction. By 1967, antiwar protests escalated in size and frequency, with notable events such as Vietnam War veterans, like John Kerry, testifying to Congress on their experiences and reasons for opposing the war.
Many Americans opposed the war for various reasons, including moral objections and skepticism about the war's objectives and impacts. Notably, Martin Luther King Jr. became an outspoken opponent of the war on the grounds of nonviolence and concern over the diversion of resources from domestic programs. Additionally, Asian American protesters emphasized the war's impact on Asian populations and chanted slogans like 'Stop killing our Asian brothers and sisters.'
However, despite the dramatic and increasing public opposition, the majority of Americans initially still supported the war, believing it was a just cause, with this belief eroding over time as the opposition's arguments became more pronounced and the realities of the war became better understood.
