How did Lenins takeover of Russia affect German war strategy?

Lenin's takeover of Russia in 1917 significantly impacted German war strategy by allowing Germany to redirect its military resources on the Western Front after Russia signed the Treaty of Brest-Litovsk in 1918. With the Eastern Front effectively closed, Germany could transfer troops and equipment to fight against the Allies in France, leading to a brief resurgence in offensive operations. However, the influx of fresh Allied forces and the subsequent failure of these offensives ultimately contributed to Germany's defeat in World War I.
