War is never a good thing. Problem that most of us have (including me, most of the time) is in remembering that war is a necessary thing.
Man is an Apex Predator (meaning, in terms of dominance). The world is being overrun by us Apex Predators. ....And you think we can get away from war?!?!??!??!??
Marshal McLuhan in his book The Media is the Message (or massage) said the future wars will be fought
in the back yards of the world. Saying major wars will be too destructive and expensive to a country's economy.
So far it's proven true except many nations are becoming nationalistic again. I just read of events in Italy in
football games where nationalistic disruptions are happening again.
Every thing old is new again.
