The 1918 treaty of brest-litovsk altered the course of world war i by -ensuring the allies’ victory over the central powers. -ending russia’s involvement in the conflict. -consolidating russia and german power in the region. -assuring the united states would join the conflict.

-ending Russia’s involvement in the conflict. 

This allowed the Central Power to concentrate all their troops and effort to the West. However, even with the improvement of the amount of troops and supplies in the area, it was too little, too late, as the US joined the war, and poured millions of fresh troops and supplies into the war, and turned the tide, routing the German troops, and ending the war with an Allied victory

hope this helps
