Why is the Treaty of Brest-Litovsk considered a difficult Bolshevik policy?

Correct answer: Because harsh terms had to be accepted to leave the war

The governing concept is the conflict between an immediate political objective and a costly compromise. After the October Revolution, the Bolsheviks promised peace to soldiers and workers because Russia was exhausted by the First World War. The Treaty of Brest-Litovsk, signed with Germany in March 1918, fulfilled the promise to withdraw from the war, but Russia had to accept severe territorial and economic losses. Therefore, option A is correct: peace was obtained, but only by accepting harsh terms. Options B, C, and D are incorrect because the treaty neither restored the Tsar, nor began the war, nor transferred full authority to the Constituent Assembly.
