Although Russia has agreed to continue the war, its diplomatic relations are complex.
On one hand, Russia, after receiving massive aid from Britain and France, did not withdraw its frontline troops.
On the other hand, Germany and Russia are maintaining some contact, and there seems to be the possibility of a peace treaty between Germany and Russia.
Now that the war has reached this point, both the Allies and the Central Powers are exhausted.
Almost 20 million soldiers have been involved in the war on both sides, and the casualty numbers have soared after the Battle of Verdun and the Battle of the Somme.
According to the current situation revealed by various countries, the total casualty figures in World War I have reached nearly 12 million, with over 5 million confirmed deaths.
This casualty figure is exaggerated. Europe's great powers had not even deployed 5 million combined soldiers before the war began, which now represents a quarter of the total fighting force.
