The beginnings will not be easy; they shall be extremely difficult. All the oligarchies' powers of repression, all their capacity for brutality and demagoguery will be placed at the service of their cause. Our mission, in the first hour, shall be to survive; later, we shall follow the perennial example of the guerilla, carrying out armed propaganda ... the great lesson of the invincibility of the guerrillas taking root in the dispossessed masses; the galvanizing of the national spirit, the preparation for harder tasks, for resisting even more violent repressions. Hatred as an element of the struggle; a relentless hatred of the enemy, impelling us over and beyond the natural limitations that man is heir to and transforming him into an effective, violent, selective and cold killing machine. Our soldiers must be thus; a people without hatred cannot vanquish a brutal enemy.
