No plans were made for a war even one year long (although highly placed individuals had their doubts and are now widely quoted about it). No German (or other) plans which existed at the start of WW1 were relevant to the way the war ended many years later. Conversely, whatever accusations were made about betrayal in the later years of the war were clearly irrelevant to the way those plans played out in 1914 when all Germans were united behind the war effort, including Socialists.
