The Bolsheviks seized power in Russia in November 1917 but they could not stop the Imperial German Army from advancing rapidly deep into Russia in Operation Faustschlag. The Bolsheviks saw Russia as only the first step—they planned to incite revolutions against capitalism in every western country. The immediate threat was a German conquest. In early March 1918, after bitter internal debate, they agreed to harsh German peace terms at Treaty of Brest-Litovsk. Moscow lost control of the Baltic States, Poland, Ukraine, and other areas that before the war produced much of Russia's food supply, industrial base, coal, and communication links with Western Europe." Britain and France felt, "The treaty was the ultimate betrayal of the Allied cause and sowed the seeds for the Cold War. With Brest-Litovsk the spectre of German domination in Eastern Europe threatened to become reality, and the Allies now began to think seriously about military intervention Russia."
