Direct aggression against Cuba would mean nuclear war. The Americans speak about such aggression as if they did not know or did not want to accept this fact. I have no doubt they would lose such a war.

The merit of Marx is that he suddenly produces a qualitative change in the history of social thought. He interprets history, understands its dynamic, predicts the future, but in addition to predicting it (which would satisfy his scientific obligation), he expresses a revolutionary concept: the world must not only be interpreted, it must be transformed. Man ceases to be the slave and tool of his environment and converts himself into the architect of his own destiny.

We have no right to believe that freedom can be won without struggle.

If you ask me the image of Latin America, there are sorne countries which oppress their peoples much more, and among the less - least oppressive, among those with which we could have perfectly normal relations without any difficulties - we could have Uruguay, Chile, maybe Costa Rica.

Work is paralyzed until it is reduced to an insignificant level. It is time to make a correction.

The revolution is not an apple that falls when it is ripe. You have to make it fall.
