Indefinite period of transition

I have thought that I would put in an effort not to criticise some historical figures and get my hands dirty. However this seems too good to resist:
Where Stalin divided "full communism" from socialism and a necessary revolution to take one to there I think as an equivalent form the conception that he places a limitation on actually getting to full communism and extends the period of transition indefinitely. The goal is thus set at a much further point rather than being defined. What is to be achieved then becomes a set-back.
At once he becomes an anti-communist!
(Did that get me too involved in the subject and persona?) And that is a subject of another post.
