To Comrade Jose Diaz.

The workers of the Soviet Union are merely carrying out their duty in giving help within their power to the revolutionary masses of Spain. They are aware that the liberation of Spain from the yoke of fascist reactionaries is not a private affair of the Spanish people but the common cause of the whole of advanced
and progressive mankind.

Fraternal greetings,

J. Stalin.
