With Russia in disarray, and the Eastern Front in a de facto armistice, we shift our attention to the West, where the French begin the latest "final" offensive.
Russia's allies--The United Kingdom, France, Italy, and now the United States--were pleased that Russia was taking a more liberal and democratic direction, but they also expected Russia to honor the commitments the czar had made to them, even though those commitments were unpopular at home. Meanwhile, the new government struggled even with its most basic responsibilities.
Even the resumption of unrestricted submarine warfare by the Germans was not enough to push Woodrow Wilson into supporting war, but the Zimmerman Telegram made it impossible to oppose war any further. Additionally, the Russian Revolution eliminated an unsavory ally, replacing him with a fledgling democracy that needed support.
