What is the difference between war and fighting?

We call war a set of battles. War is a large volume involving many battles. Take, for example, the incident in which Pearl Cabernet was attacked by Japan, Japan won its opening battle, but lost in World War II, which involved many such battles.

A fight that involves many conflicts.

There is a proverb in English that says `lose the battle but win the war`. This means that even if part of the war is lost in the war, victory in the war as a whole.
