It seems we are splitting hairs here on the definition of "war" and missing the actual message. Since you brought it up again.

War (Noun) " - a state of hostility, conflict, or antagonism

  - a struggle or competition between opposing forces or for a particular end 

  - a struggle to achieve a goal: 

"

War (Verb): " - to be in active or vigorous conflict

- to carry on active hostility or contention

"

The point still stands. War is an isomorphism for competition, conflict and tension between parties. One could probably use something like category theory and prove it.
