As the war entered 1917, there were serious questions about what was likely to happen.
Could France and England, especially France, continue to wage war after suffering horrendous casualties at Verdun, the Somme and elsewhere? France would go through a series of prime ministers in 1917 and even a series of mutinies in the French Army in May, but they had rejected the German peace feeler sent to Woodrow Wilson in 1916.
Could Germany continue fighting a multi-front war? Not only was it suffering huge casualties in France, it had to shore up the Austrian forces in the east which had suffered high casualties against the Russians and seemed to be mired in a static front against the Italians.
Romania was essentially out of the war, having been almost overrun in only a few months by the Austro-German-Bulgarian forces. Fighting continued elsewhere in the Balkans.
