Your position is that Vietnam has been destroyed?

Because the US seems to be doing a lot of trade with a communist country which calls itself Vietnam. And that country seems to be in rather better shape than Cuba, with the biggest difference the US embargo on the latter.

The Cubans who recently died because there's no power for their ventilators didn't die because of Communism, but because the US is preventing oil from getting to the country. The US could do the same to Haiti, or the Bahamas, or Jamaica. Gunboat diplomacy is back on the menu.
