Cuba has some of the best food sovereignty for such a small landmass, they import a lot of rice but all the fresh produce and most of the meat comes from local community gardens. They're under the harshest sanctions on earth, only a handful of countries trade with them because USA threatens to attack those who trade with them. Like how USA recently stole an oil tanker from Venezuela because the oil was sold to Cuba already. The same applies to food and all basic necessities, China Vietnam and a few other countries in South America trade with them despite the threat of military intervention. The fact they have survived this long against the largest military empire the world has ever witnessed is a testament to their strength as a people, education and healthcare are free, they produce the most doctors per capita on earth and supply medical aid to many other countries in Africa and South America. They preserve and celebrate their own culture instead of adopting consumerism like other "socialist" countries. We should really look to Cuba for answers to address our own problems, their local politics is far more democratic and gives people far more say over their own communities, they accept plenty of refugees but those refugees integrate and assimilate to their culture with little resistance.
