The "New World" was destroyed completely by the European invasion, with the governments in place created by the ones who broke down, nearly destroyed every trace of the cultures already in place.
What has managed to survive the ravages of time in Mexico is astounding. Even the conquering Spanish who destroyed the Aztec culture, built in the place of older civilizations, acknowledged the city was larger than any they had seen in Europe. Then they got right to work tearing down as much as possible....
With enough time archaeologists, anthropologists are going to be able to determine so much more than they have already learned about the city, the civilization. Mexico City is fascinating.
Cuban medical researchers have had to work practically in the dark, with access to almost everything they need placed beyond their reach through the power, albeit illegal in international law, of the US embargo.
Other countries have protested this from the first, as it actually contradicts their freedom to their own free trade, since it blocks their commerce with Cuba if any of the products contain any elements connected to the US, as in patents, or materials, etc. Once that is established, their ships, delivering the products to Cuba are forbidden to enter any US ports for 6 months.
The entire world, except for Israel, and possibly 1 or 2 other areas, like the Marshall Islands, or Guatemala, etc. have voted to end the embargo for decades at the U.N.
So still Cuba has persevered, through ingenuity, like the Cubans who learned how to duplicate parts to keep the Cuban US-made 1950's cars!
They are definitely extraordinary scientists, and when the time arrives, they are going to be celebrated internationally! ⭐️⭐️⭐️
