Here's why:
* The Soviet Union was a totalitarian state: Stalin's power rested on propaganda and control, not on logic or reason. While he could use the language of logic to justify his policies, the reality was often very different.
* The realities of Soviet life were often brutal: Forced labor, purges, and widespread poverty contradicted the rosy picture painted by Stalin's propaganda. This made it difficult to present a logically consistent argument for his actions.
* Stalin's policies were often contradictory: He claimed to be building a socialist utopia, yet he ruthlessly suppressed dissent and enforced a cult of personality. This contradiction made it challenging to present a logically coherent narrative.
* Lack of independent information: The Soviet populace had limited access to information outside of state-controlled media. This meant that even if Stalin's arguments were flawed, people had little basis to challenge them.
Therefore, while Stalin could use logical-sounding language, his ability to effectively use logos was severely hampered by the stark contrast between his rhetoric and the harsh realities of life under his rule. He often relied on emotional appeals and fear to maintain control, rather than relying solely on logic and reason.
