What are some potential benefits and potential costs of total war, and do the potential benefits ever outweigh the costs?

There are huge loss of life and property in a total cost.

Explanation:

The concept of " cost war" means that there are no limits in that war. Anyone can be attacked in that war and there is no restriction on the type of weapon also that is to be used in that war.

So the benefits of such a war can not be any but there can be only cost of the war because it can only lead to the harm of the life and property of the people who are involved in that total war. Benefits never out weigh the costs.
