Answer
World War I was not commanded by Moltke. Moltke the Elder commanded the Prussian and German armies in the Austro-Prussian War of 1866 and the Franco-Prussian War of 1870-71, while Moltke the Younger commanded the German army in the Second Boer War of 1899-1902. By the time World War I broke out in 1914, Moltke the Younger had retired, and the German army was commanded by Erich von Falkenhayn.
