You continue to state as fact something you have still failed to prove, that some mythical puppet Ukrainian state would be a 'deadly threat' to the Soviet Union, and now a similar threat to Poland. More to the point you now concede Hitler refused to create such a beast when he had the chance. To claim a puppet state of 450,000 people in a back water of central Europe is a credible destabilizing factor in the face of Totalitarian states is ludicrous. Was there free border access between Germany, Poland and the SU? Did they have credible free press's? All three counties had well deserved reputation's for nipping any anti-government opposition in the bud, so where is the 'deadly threat'? No reason you say for the SU to come to the aid of Poland, then why enter talks to do that very thing? Stalin concluded the West wasn't serious because they were not prepared to give them the Carte Blanche to do as they please along her borders the way Nazi Germany would. To buy into the rest of your post you have to buy into the Stalinist Communism paranoia as being logical, which it wasn't. You seem to forget what Lenin, Trotsky and Stalin was saying at the same time Churchill spoke, the whole world revolution thing. Ring any bells? Just how could Stalin know in the late summer of 1939 what the Allies would do in a war not yet declared and how could that inform him to distrust the Anglo-French alliance. Did Stalin somehow forget Britain was a naval power? Really? Of course they aren't going to deploy dozen's of divisions initially. By the way in 1914 Imperial Russia invaded Germany first, not the other way around and the French offensive began within days of German movements.
