Like other organisms, humans have a certain genetic endowment (apparently varying little in the species, not a surprise considering its recent separation from other hominids). That determines what we call their nature.

Modifying the core institutions of the society is no small challenge.

There's something deeply rooted in American culture. You can pretty much identify what it was. You take a look at the history. It was internal conquest. You had to defend yourself against what the Declaration of Independence, Thomas Jefferson, an enlightened figure, called the attacks of the "merciless Indian savages," whose known way of warfare was torture and destruction. Also you had a slave population, you had to protect yourself against them. You needed guns.

We have to remember that literally within months after Castro's taking office the planes from Florida were beginning to bomb Cuba. Within a year, the Eisenhower administration secretly, but formally, decided to overthrow the government. Then came the Bay of Pigs invasion. The Kennedy administration was furious about the failure of the invasion and immediately launched a major terrorist war and economic war that got harsher through the years. Under these conditions it is kind of amazing that Cuba survived.

A 1998 study was done in Hebrew by an Israeli scholar, Yosef Grodzinsky, and the English translation of the title is Good Human Material.

These policies were somewhat complementary to the U.S. policy of pressuring England to allow Jews to go to Palestine, but not allowing them here. The British politician Ernest Bevin was quite bitter about it, asking, "if you want to save the Jews, why send them to Palestine when you don't admit them?"
