The U.S. directed the war against South Vietnam. There was a political settlement in 1954. But in the late '50's the United States organized an internal repression in South Vietnam, not using its troops, but using the local apparatus it was constructing. This was a very significant and very effective campaign of violence and terrorism against the Vietminh - which was the communist-led nationalist force that fought the French. And the Vietminh at that time was adhering to the Geneva Accords, hoping that the political settlement would work out in South Vietnam.

That was the reason why very few people fleeing the rise of fascism in Europe, especially in Germany, could get to the United States. And there were famous incidents like with the MS Saint Louis, which brought a lot of immigrants, mostly Jewish, from Europe. It reached Cuba, with people expecting to be admitted to the United States from there. But the administration of Franklin D. Roosevelt wouldn't allow them in and they had to go back to Europe where many of them died in concentration camps.

The US is a business-run huckster society, and its primary value is deceit.

The Sanders campaign showed that a candidate with mildly progressive programs could win the nomination, maybe the election, even without the backing of the major funders or any media support. There's good reason to suppose that Sanders would have won the nomination had it not been for shenanigans of the Obama-Clinton party managers. He is now the most popular political figure in the country by a large margin.

If you believe in democracy, why shouldn't you know what the government is doing?

The "end of history" has been proclaimed many times, always falsely.

It may be beyond the limits of human intelligence to understand how human intelligence works.
