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.

A war involves many battles.

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.
