Germany was in fact defeated in 1918 ... The German forces on the Western Front were still 'in good order' but were retreating fast. The 'Fourteen Points' made the decision to seek an armistice less unpalatable than might otherwise have been the case, but the suggestion that they 'forced Germany to surrender' is wildly inaccurate. It was the top Germany who by late September 1918 wanted peace, at almost any price. They were also haunted by the 'spectre of Bolshevism'.
