The Communist policy was that the war was not the time for the revolution, that until victory in the war was won the goal had to be the defeat of the Francisco Franco forces, not the abolition of capitalism, which was to be addressed once the war had been won.
Политика коммунистов строилась на том, что во время войны не было времени и возможности для социалистической революции, и потому целью должна быть победа над Франко, а не свержение капитализма.
