Here is your answer: It was because of the harsh conditions both sides of the war had men dying not from the war but the coldness, lack of food, and diseases or sicknesses so they decided to quit the war because of how much of their men were dying because of the horrible conditions and that's why they called it the "cold war".
I think the answer is the evidence or statement. I am not really sure what you are trying to ask but if this was a question he answer would be either evidence or statement.
