An attempt at perspective:
The decision to go to war, whether a formally declared one or not, will almost always result in the death of non-combatants.
The decision to attack is then the key tipping point. All that follows is to various extents out of control - subject to variable human nature, training, cultural differences, circumstances - and the 'fog of war'.
Where are these decisions made - and by whom.
An article here on Common Dreams suggests, rather convincingly, that Trump is a 'malignant narcissist' - in effect, a sociopath.
This article points out Obama acted in precisely the same way - maybe his PR was better - but actions - and results - same.
Jacques Cousteau, the great explorer, said that at sea, the human being acted like a savage. One wonders if civilized man is any better.
Fridtjof Nansen, another world class explorer and winner of the Nobel Peace Prize, said nearly identical words in regard to nation states - that they behaved like the predators of the wild natural world.
Even before industrial war - Ghenghis Khan, and a truly long list of like minded would be conquerors have killed non-combatants in the millions, literally.
At the tribal level - same.
Eric Margolis' book, "War at the Top of the World', especially the second half, where geopolitics is the focus, confirms this view of nation states as always having to guard against enemies, both real and perceived, and often, it is the nation state which actively turns to aggression and expansion, for whatever reason, this leads to war, formal, or undeclared, or proxy, and the same loss of life of non-combatants results.
There is another article here on Common Dreams suggesting that we are collectively in denial - of the history of the United States.
I would also suggest there is denial at a more universal level.
We are all savages - it's genetic.
If there is any hope for any future at all for the human race, it may be that savages do possess a sense of self-interest - and of survival - and that now, this means an end to our longest and in many ways most cherished occupation - war.
I will not comment on the likelihood of this realisation occurring any time soon.
