In 1964, President Lyndon Johnson asked Congress for authorization to use military force in south-east Asia. His resolution passed unanimously in the House, and only two voices dissented in the Senate. As for the public, 77% of Americans said they trusted the government to do what is right, and more than 60% supported war.
It is common today to hear that the US war in Vietnam was unpopular, but it certainly did not begin that way. It took several years, billions of dollars, tens of thousands of deaths, and constant anti-war mobilization before Americans changed their minds.
The reality is that Americans have historically backed their government’s wars. Let’s not forget that most Americans not only falsely believed that Saddam Hussein was responsible for 9/11, but also supported the illegal US war on Iraq. A month after the invasion, support for the war increased to 74%.
Not any more. President Donald Trump did not even bother seeking congressional approval to attack Iran. Polls show that the majority of Americans oppose the Israeli-US war, and only 17% trust the government to do what is right. And the war is only a month old.
