Where exactly did the USSR go wrong and what would've you done

...

Balts and Jews were overrepresented as bolshies, but it's not a conspiracy.

Almost like Jews were in a particularly precarious position in the late Russian Empire and tended to be on the side that opposed pogroms.

Or that their shitty treatment throughout history caused them to reject mainstream political discourse and that’s why they’re over represented in both radical right and left wing political movements.

I think the Menshies had an even bigger Jewsish overpresentation anyway.

But its not like Bolsheviks were a "miniature Russia" in any way, industrial workers were overpresented as heck as well. I can't find any definite information on it, but I would guess that the "intelligentsia" or some relatively well-to-do group was also overpresented compared to the general population.

You misinterpret the "withering away" that happened in USSR. It is not natural continuation of transition to Communism, but degeneration of Socialism back into Capitalism.

See here (and following posts):

> No Communist ever (Lenin included) wanted to achieve Anarchism. The idea is a "stateless society" - which is understood differently (in much more precise way) from vague Anarchist understanding of the term. "Stateless society" is when state (in Marxist understanding of the term; see Engels) simply cannot function, since there are no different classes involved in production (economic life). That doesn't mean that all the trinkets that we associate with the State today are gone - as Anarchists expect. In fact, if Anarchist understanding of the State is used, it is not abolished, but becomes all-pervasive, encompassing all aspects of social life. I.e. ultimate totalitarianism (except real, not the fake one of Fascists - who left crucial bits of social life in private property of Capitalists).

They should have developed long range bombers and nuclear weapons sooner.

Early Stalinism suffered from being simply too violent. If you're conducting purges where you send "shoot so many people" quota regardless of proven crimes (Order 00447), you're doing something wrong . The latter day soviet union, from a disconnect between the party elites and the people, which allowed certain party elites to hijack power and dissolve the soviet union all the while filling their pockets at the expense of the people.

Quotas were the absolute maximum of people that locals were allowed to persecute under emergency law.
