Cuba intervened into numerous conflicts during the Cold War. They sent medical and military aid into foreign countries on various occasions. The interventionist policies of Cuba during the Cold War were controversial and resulted in isolation. Cuban leader Fidel Castro held power to militarily intervene in other countries that he perceived to be ruled by a tyrant or despot. Castro justified intervention into foreign conflicts stating: "Our Revolution is not a revolution of millionaires. Instead, it is one carried out by the poor, and is one which dreams of ensuring the well-being not only of our own poor, but rather of all the poor in this world. And that is why we talk of internationalism."
