A very big question!!!
Without Lenin's example, it is entirely possible that the German governmental structure would not have collapsed in the way it did in November 1918. Bear in mind that it was not only the Kaiser's monarchy which disappeared, but every other monarchy in the country. By no means all the other rulers were regarded as personally culpable in the same way as the Kaiser. The Crown Prince fled to Holland at the same time as the Kaiser, but was not granted political asylum beforehand and so was interned by the Dutch for a period. He did not return to Germany until 1923.
