Am fighting as Germany vs. a coalition of UK/Ottomans/Russia/et al. Originally, the UK was the war leader. Then Russia joined the war (they weren't part of the alliance originally) and became the war leader. The Russian, Ottoman and other smaller allied lands have been 100% occupied and the UK army has almost completely been wiped out. However, I am only able to negotiate with Russia since it is the war leader. My warscore is at 100%, but the accumulated territories set as war goals is equal to almost 300 (for each completely occupied country this war goal value is less than 100%). Russia refuses to offer any peace. Germany occupies 500+ enemy provinces at this point. How do I negotiate an end to this war?
