Human language is nothing like the signalling systems of other animals.

Since November 8, 2017 the United States is literally alone in the world in first of all refusing to join in efforts to do something about climate change, but even worse, dedicated to making the situation worse. Every part of the world is trying to do something. The United States alone is trying to destroy it, and it's not just Trump, it's the whole Republican Party. You just can't find words for it. And it's not reported. It's not discussed.

After the first International Days of Protest in October, 1965, Senator Mansfield criticized the 'sense of utter irresponsibility' shown by the demonstrators.

I think religion has often played a very positive role. Take western civilization, the Catholic Church has played an honorable role in helping those in need. In contrast, the US carried out a virtual war against the church in central America in the 1980's primarily because prime elements in the church were working with great courage and honor to help those in need. And to organize them to help themselves.

I think it's just been a core part of the Cuban revolution to have a very high level of internationalism. I mean, these cases you've mentioned are cases in point, but the most extreme case was the liberation of Africa. Take the case of Angola for example, and there are real connections between Cuba and Angola-much of the Cuban population comes from Angola.
