You tell us about it.
Not saying you're wrong. You're very clearly not wrong - Russia started industrialising in the late 19th C. But to what extent does Idaho's error in not acknowledging this make his subsequent reasoning wrong? So the question here is 'how had industrialisation in Russia progressed by 1917, and what challenges did it still face when the dust settled after the civil war'? How did Stalin's policies advance industrialisation, and what was the base he was working from? How did that base compare to the bases in other countries, and how did his progress compare?
If you're going to nitpick, at least enter a positive contribution.
