You provided an opinion - not fact.Cryhavoc see my last post. Tell me what you know that the Entente leaders did not know.
Britain and France did not suffer a turnip winter Germany had - the 2 Empires had access to the worlds trade and that would include the USA who would still want to trade with them.
While the defeat of Russia had taken the pressure off it - both Britain and France had by 1917 built their industries and Britain had finished building its continental army
Either side could have blinked for sure - but the Entente did not want to seek terms with the disadvantage of having French and Belgium territory in German hands and Germany could not force the issue from 1915.
So we have an impasse and its my opinion that things would drag on into 1919 before the 2 sides sought terms.
