80 years since the assassination of Trotsky by a Stalinist agent in Mexico

It is 80 years since Trotsky was assassinated by a Stalinist agent in Mexico. Today our task is to rebuild the ‘world party of socialism’ on the foundations of the 1938 Transitional Program and fulfill the goal of world socialist revolution against dying capitalism’s drive to destroy nature and humanity. Here is Trotsky rallying his supporters for a new international to fight the cause of world revolution in 1935. Forward to the revolution!
“The new parties and the new International must be built upon a new foundation: that is the key with which to solve all other tasks. The tempo and the time of the new revolutionary construction and its consummation depend, obviously, upon the general course of the class struggle, the future victories and defeats of the proletariat. Marxists, however, are not fatalists. They do not unload upon the historical process those very tasks which the historical process has posed before them. The initiative of a conscious minority, a scientific program, bold and ceaseless agitation in the name of clearly formulated aims, merciless criticism of all ambiguity those are some of the most important factors for the victory of the proletariat. Without a fused and steeled revolutionary party, a socialist revolution is inconceivable. The conditions are difficult; the obstacles are great; the tasks are colossal; but there is no reason whatever to become pessimistic or to lose courage. Despite all the defeats of the proletariat, the position of the class enemy remains a hopeless one. Capitalism is doomed. Only in the socialist revolution is there salvation for mankind.”
