3) Consider whether Lithuanian Jews might actually have preferred continued Lithuanian independence to either Soviet or Nazi rule
I have never said that Jews in Lithuania specifically rejected the the option of continued Lithuanian independence.
What I have said is that in 1939 and 1940, the option of continued Lithuanian independence, free of the domination of either the Soviet Union or Germany, was no longer available. It was clear to anybody with eyes to see that Lithuania would fall under the domination of one or the other of those two powers, either as a satellite state or by being totally absorbed.
Given those two options, Jews in Lithuania as a group clearly preferred the option of domination by the Soviet Union, since its governing ideology was Jew-friendly in theory, and in practice had allowed Jews to achieve a higher socio-economic status than before the First World War, whereas the governing ideology of germany was thoroughly hostile to Jews, and so was its practice.
That preference put Lithuanian Jews at odds with the great majority of the inhabitants of the country, for whom Soviet domination brought no benefits whatever, since the alternative of German domination did not pose a threat to them, in the way that it did to the Jews of Lithuania.
Once Lithuania came under Soviet domination, a substantial section of the Lithuanian population, particularly the more nationalistically-inclined population elements, looked to Germany as the only power that could overthrow Soviet power and give Lithuanians the chance of a life free of Bolshevik tyranny, even if only as a satellite of Germany, which was not all that palatable to nationalist Lithuanians, but for them the lesser of two evils.
Those Lithuanians who looked to Germany as their potential saviour from Soviet domination could see that the Jews of Lithuania were totally opposed to a German takeover, because of the danger it posed to them, and wanted the status of Lithuania as a part of the Soviet Union to continue (at least as long as Germany posed a threat to them), not because they liked the Bolshevik social and political system (except for a minority of the youth who were revolutionary socialists by inclination), but because being part of the Soviet Union kept Lithuania from coming under German domination.
It was the impression of the Jews of Lithuania wanting to retain Soviet rule and opposing its overthrow by Germany, ie the exact opposite of what was desired by nationalist Lithuanians, that caused the latter to resent and hate the Jews living in their country, and to regard them as traitors and collaborators who deserved to be punished.
That is what Dina Porat meant when she talked about "tragically opposed political orientations". It was not just a matter of impressions, false or true, but real differences in vital interests between two population groups, one constituting the majority and the other a minority.
Sid, you need to try to grasp the essential meaning of what Porat is saying, rather than quibbling over individual words.
I can well accept that many Jews of Lithunania did not like some of the essential features of Soviet rule and the accompanying bolshevisation of the social and economic systems, for example the loss of personal liberty and wealth, and of freedom of economic activity, even though they could see that Soviet rule was the lesser evil for them than German. Under the circumstances, I can understand why many wanted to avoid both Soviet and German rule by emigrating, and did so if they had the opportunity and means. But most could not emigrate, but had to stay in Lithuania, and in that situation their only chopice was to continue to support Soviet rule and oppose its overthrow by germany, which as stated brought them into direct conflict with the aspirations of Lithuanian nationalists, and probably of most Lithuanians who would have preferred German rule to Soviet.
The 1930s were characterised by exactly such poisonous, simplistic generalisations about Jews and we know the result of that.
It was not "poisonous, simplistic generalisations", which implies some sort of falseness and unreality, that led to the massacre of millions of European Jews, primarily in Eastern Europe, between 1941 and 1944, but very real conflicts of national interest.
Those conflicts were very apparent to observers in 1919, in the context of the Paris Peace Conference that was underway, and led some of them to predict a disaster for the Jews of Eastern Europe if the conflicts were not resolved. The conflict was particularly apparent between the Polish delegation to the Conference, led by the judeophobic and germanophobic Polish nationalist Roman Dmowski, and an unofficial East European delegation led by the orthodox Jew and General Zionist leader Menachem Ussishkin (who had come to the conference as part of a Ukrainian delegation, with the function of representing Ukrainian Jewry, but had left it to set up the unofficial delegation of all East European Jewry).
The main clash was over the political status that Jews were claiming for themselves in the new states such as Poland, essentially as a separate nation with extraterritorial rights. So heated did those clashes become that the chief adviser to the British delegation, James Headlam-Morley, went to the Anglo-Jewish leader, Lucien Wolff, who was at the Conference with the official group of Jewish observers from the western countries, to ask if he could do anything to hose Ussishkin down. When Wolff replied that Ussishkin was out of control, Headlam-Morley commented; "Then they will all be murdered".
The above conversation is known from Wolff's Peace Conference Diary.
Headlam-Morley got it right; the clash between Jewish nationalism and that of the emerging East European peoples, including the Lithuanians, was not resolved but grew worse, and as a result the Jews were all murdered, as Headlam-Morley had predicted.
The above-mentioned Menachem Ussishkin later got involved in an incident that is highly revelatory of the complex relationship between Jews and Bolshevism. After the conclusion of the Paris Peace Conference, Ussishkin emigrated to Palestine, where he became Acting Chairman of the Zionist Commission.
On 13 April 1920 there was a conversation between Ussishkin and Sir Ronald Storrs, British Governor of Jerusalem from 1917 t0 1925, that is recorded in the Central Zionist Archives: L/3/256: April 13, 1920, and is quoted on page 146 of the 1986 book "The Siege: The Saga of Israel and Zionism" by the Zionist sympathiser, the late Conor Cruise O'Brien.
This is what Cruise O'Brien wrote:
Later in the course of his long an increasingly emotional speech, Ussishkin said: "........Czar Nicholas also did not interfere with the pogroms, he also oppressed us. Yet does Your Honour see what befell him? In his place sits Trotsky. All our enemies in the world and in the land of Israel will also meet such an end".
Here Ussishkin was making a veiled threat to Storrs. He was complaining about the latter's failure to prevent Arab anti-Jewish riots in Jerusalem at the beginning of April 1920, in which small number of Jews (and Arabs) had been killed. He was comparing Storrs' attitude to that of Tsar Nicholas, who had similarly failed to prevent the pogroms in pre-Rovolutionary Russia, and implying that the same thing would happen to Storrs as happened to Nicholas.
Ussishkin's words reveal a number of significant features of the ideology of this Orthodox Jewish Zionist (definitely not a Bolshevik, or any other sort of Jewish leftist):
1. The Russian Revolution was retribution for the anti-Jewish actions and policies of the Tsar, and the Russian ruling class as a whole;
2. The Russian Revolution was a Jewish action (significantly, Ussishkin names the Jew Trotsky as the successor to the Tsar, as the man with the real power, not the non-Jew Lenin);
3. The Russian Revolution, and the overthrow of the Tsar and the previous ruling class, was a model for what the Jews wanted to do to all those in the whole world whom they regarded as their enemies.
I have no doubt that the views of the Zionist leader, Menachem Ussishkin, were representative of those of a large number of nationalistically-inclined Jews, particularly in eastern Europe. Given those attitudes, it is easy to see why there was such conflict between Jews in Eastern Europe and the peoples among whom they lived, including the Lithuanians, and why that conflict had such a violent and murderous resolution.
Sid, I doubt that we will see eye to eye on this issue. However, I urge you to read the books I have recommended to you, and try to get some information about the persons I have mentioned, and their ideas and actions. That will help you to gain a more nuanced view of the fate of the Jews in eastern Europe in the first half of the 20th Century, rahter than the simplistic back-and-white view that you seem to have now.
