Aleida Guevara, daughter of the Che, talks about her experience with Cuba’s international medical brigades and the importance of solidarity among peoples: “That gives you extraordinary force as a people, truly, because you can say ‘We are capable, we are capable of going to any place in the world where our help is needed’. Neither their skin color, nor their religion matter, not even what they think matters. It doesn’t matter. We can simply be useful and we are. That is one of the most beautiful things of the socialist revolution.”
