Assaults and terrorism in indiscriminate form should not be employed. — Ernesto Che Guevara

We consider that the Cuban Revolution contributed three fundamental lessons to the conduct of revolutionary movements in America. They are: (1) Popular forces can win a war against the army. (2) It is not necessary to wait until all conditions for making revolution exist; the insurrection can create them. (3) In underdeveloped America the countryside is the basic area for armed fighting.

War is always a struggle in which each contender tries to annihilate the other. Besides using force, they will have recourse to all possible tricks and stratagems in order to achieve the goal.

The education of the guerrilla fighter is important from the very beginning of the struggle. This should explain to them the social purpose of the fight and their duties, clarify their understanding, and give them lessons in morale that serve to forge their characters.
