A man is also the child of circumstances, of difficulties, of struggle. Problems gradually sculpt him like a lathe sculpts a piece of metal. - Fidel Castro

President Ho Chi Minh, understanding the extraordinary historical importance and the consequences of the glorious October Revolution, and assimilating Lenin's luminous thought, saw clearly that in Marxism-Leninism we could find the teaching and the path that had to be followed to find a solution to the problem of the peoples oppressed by colonialism.

What is the history of Cuba but the history of Latin America? And what is the history of Latin America but the history of Asia, Africa and Oceania? And what is the history of all these peoples but the history of the most pitiless and cruel exploitation by imperialism throughout the world? At the end of the last and the beginning of the present century a handful of economically developed nations had finished partitioning the world among themselves, subjecting to its economic and political domination two-thirds of humanity, which was thus forced to work for the ruling classes of the economically advanced capitalist countries.

The USSR self-destructed in an incredible way. The responsibility for that self-destruction undoubtedly lies in the hands of the country's leaders, those who led that nation. Now, some of them were aware they were destroying it and others were not. That is what I was trying to say, more or less, and we saw it all from the beginning.
I cannot say Gorbachev played a role in which he was aware of the destruction of the USSR because I have no doubt that Gorbachev intended to fight to improve socialism.
We approved of Soviet efforts to improve socialism in the USSR. But we could not approve of, and never would have agreed to, not only the destruction of socialism in the USSR, but also the destruction of the USSR itself. That inflicted terrible damage on all peoples of the world and created a bad situation for the Third World in particular. Imperialism would have been able to disintegrate the Soviet Union, had the Soviets not destroyed themselves, had those responsible for the strategies and tactics and for the country's political and government policies not destroyed the country. In other words, socialism did not die from natural causes: it was a suicide, socialism was murdered. That is what I meant.
