During the First World War, many of Germany's Jews actually did lend their support to the German cause, and German victory was seemingly inevitable in 1917, especially when the Russian front began to collapse and the Bolshevik Revolution in Russia ended that nation's part in the war effort against the Germans. But in 1917, something else happened. Lord Balfour signed a declaration assuring the Jews a homeland in Palestine if Britain won the war. The Ottoman Empire, a vestige of which remains as modern Turkey, controlled Palestine at the time, and the Ottomans were allies of the Germans. It was Jews in Germany who through their capitalism controlled much of the country's industrial power, and once this declaration was signed, these Jews, along with their lower-class kinsmen, became hostile to the German war effort, becoming more or less a fifth column in German society. At the same time, Jewish leaders in Germany instigated and organized labor disruptions at the German munitions factories. With all of this, and with American entry into the war on behalf of the British, Germany's fate was sealed and her defeat was assured.
After the First World War was over, and the Kaiser removed by what more or less amounted to treason, a "Republican" form of government was instituted in Germany amidst much prolonged political and civil strife. This new government is now referred to as the "Weimar Republic", and it lasted until 1933. This republican government, dominated by the "Social Democratic" parties, was actually very socialist in nature, and had large factions of communists and communist sympathizers, but it was not itself truly communist. The Weimar Republic was marked by rampant inflation and a cowering of the German people to the extravagant reparations and demilitarization demands resulting from losing a war which Germany did not start. Along with those reparations came the loss of much historically German territory, which Germany was forced to cede to the whims of the victors. The monetary inflation itself was to a great degree the cause of the tremendous reparations burden. The Weimar government also suffered heavily from a failure to reel in the communists and communist factions of the controlling political parties. The communists stridently attempted to install a government of their own during these years, and actually succeeded in doing so by force in Bavaria, at least temporarily, and again in a part of the Ruhr region. These communist uprisings, along with others in Hamburg and in Saxony in the early 1920's, were not put down by the Weimar government, but by coalitions of patriotic Germans known as the Freikorps, and factions of the military operating independently and in spite of the Weimar government.
The Jewish hand in all of this civil discord in Germany could not go unnoticed. Many of the communists in Germany were lower-class Jews, and a great majority of the Jews were communists. Additionally, due to the rampant inflation, for it literally did take a wheel-barrow full of money to buy a loaf of bread, the only people who were able to buy either property or goods were those who could obtain money from outside of the country. In 1914, a German mark was valued at around twenty-five cents of American money. In 1923, one million units of that same currency were only worth a mere dollar. During this period many German families were forced to sell everything they had in order to survive. Hence the upper-class Jews with foreign financial connections were able to buy up much of Germany's material wealth for incredibly low sums. Jewish carpetbaggers abounded, consuming the nation like so many parasites consume a cadaver. All classes of Jews in Germany had a feast in the Weimar years, glorying in their perceived victory over the heart of European Christendom, for now they would own it. While all of this transpired, there was an earnest endeavor by the radical communists, who had much political influence in the major parties which were Socialist themselves, to stifle all serious political opposition.
Only 30-40 years ago one could hardly find a single restaurant with Jewish cuisine in France. Today Paris is home to approximately 350,000 Jews, Marseille - 70,000, Lyon - 25,000, Strasbourg - 16,000, Toulouse - 23,000, and Nice - 20,000.
