I think that
@Lemontree is touching on a very interesting area, which is where love of our surroundings and pride in the positive qualities and achievements of our neighbours and community gets twisted into a sense of entitlement.
and the other side of it where a malignant sense of victimhood is spread and used (by high functioning psychopaths and narcs) for their own benefit. This greivence is directed towards a scapegoat on whom all of our troubles, whatever they are can be blamed.
what follows isn't trying to bash
@Simply Simon or anyone who lives in Israel.
During the 19th century, there was a romanticist growth in nationalisms and ideas that people who lived within the lines drawn on maps were actually different races, had distinct characteristics and needed different things to survive.
There was also a backlash against the incredible wealth being generated by laissez faire liberalism and industrialization. Napoleon had earlier berated England as "a nation of shopkeepers" and some amongst the Prussian hierarchy spoke and wrote about the warrior spirit being the correct one and trade leading peoples to be weak and degenerate - certainly war had gained much for the Prussian hierarchy, with the annexations culminating in the wars against the Hapsburgs and Denmark in the 1860s and France in 1870, consolidating the over 1,000 independant cities, principalities, cantons and manors that had existed prior to the Napoleonic wars, into one - with them in charge. The same had happened at the same time in Italy with the House of Savoy at the top.
Parallel with this, was a romantic (and thuggish) Jewish movement, pushing the idea that Jews could not live ammongst none Jews, that jews could only flourish with their own state.
Enter the run up to the dispute between the Hapsburgs and the Serbian leadership, which escalated to become the first world war: The War To Make The World Safe For: Lenin & Trotsky, Benito Musolini, Generalisimo Franco, and Adolph Hitler...
Romanov Russia was THE anti Semitic power of the time. How to sway the prosperous Jewish businessmen and bankers to fund the war aims of an alliance which included the Tzar?
British minister, Balfour came to the rescue, with the promise of a small province which was then part of the Ottoman Empire, as a "Jewish Homeland". Financing for the alliance including the Tzar was secured, and the seeds for stories of "Jews selling Germany out" were sown.
Exactly what cooperation there might have been in coordinating and funding Lenin and Trotsky and getting one via Germany and the other from America, into Russia, is a very interesting question, that I don't know much about.
What about Zionism?
Is the darkest end of it's ideology so different to that of the NSDAP? The idea that "a people" cannot live alongside others, but must live separately, and have "lebensraum" (sorry if my spelling is incorrect).
Very controversially, it seems that in 1933, post Reichstag Fire, some German Zionists did see a close similarity and so did at least one senior NSDAP thug, Leopold von Mildenstein, who visited Palestine had a commemorative medal struck to mark the occasion and wrote up the story in the NSDAP party rag "The Assault". That much appears to be factual, the rest of the story appears to be hotly contested.
