If economic developments continued as at present, before the winter was out Germany would be like a powder barrel that a single spark could set off. The Middle parties in the Reichstag would be hopelessly split, and the world would have the choice between a Bolshevist Germany and a National-Socialist Germany. A Bolshevist Germany would repudiate everything – Reparation debts and private obligations too. Those who, with a helpless shrug of the shoulders, had signed the Treaty of Versailles and the Dawes Plan and the Young Plan had been giving bad cheques. A National-Socialist Germany would never sign cheques it could not honour. It would not make the political payments, because it would not honestly be able to; but, like any honest merchant, it would honour all obligations to repay private foreign loans and investments. If the world insisted on the political payments being made, then Germany would go under.
The Bolshevization of Russia had already given the civilized world a jolt; if Germany became an annex of Bolshevist Russia, Western civilization would get a much worse and probably fatal jolt. Even Oswald Spengler, who had at least given the decline of Western civilization 300 years to complete itself, would then prove to have been an optimist.
