Explanation: In the 1960s and early 1970s, the USA was involved in what’s known to us as the Vietnam War, wherein we backed an anti-communist military junta against the single-party state of North Vietnam. Whatever the morality of what side we took there, our conduct was also horrific, owing to a combination of factors which we needn’t necessarily go into here. Suffice to say, we killed hundreds of thousands of Vietnamese in horrible ways for dogshit reasons, and depending on whether you want to count the war’s total human losses as our fault, potentially millions.

When North Vietnam united the country by force, we refused to ‘play ball’ with the new government and maintained the trade embargo we had imposed during the war.

After the Soviet Union fell and the Cold War ended, a mixture of lessened international tensions, increased skepticism of the value of the Vietnam War to begin with in US culture, and a mutual distrust of China (who had attacked Vietnam shortly after we did, also unsuccessfully) led to the US ending the trade embargo in 1994 - 30 years after it was first imposed. The US is now one of Vietnam’s largest trading partners, and includes (limited) security cooperation as well.

War. What is it good for?

Says more about the stupidity of the Vietnamese. After decades of horror inflicted on them by the Americans, they are running into their arms. Biggest example of breathtaking self harm ever
