And how many times do I have to repeat this part? The amount of sabotage going on was almost certainly not enough to cause mass famine.
Mass famine would require mass action. If there was enough rebellion to starve the country, it would have deposed the Soviet Union entirely.
The maximum number on the people actually having rebellions was what? 150,000? That's nothing.
No, the famine was caused by misaligned economic incentives which fucked the entire system.
Also don't forget that a very similar famine resulted from mao trying the same shit. This is not a uniquely Soviet phenomenon.
