@Ray B
reading your last comment. I came to notice with all other members related posts, that one word about this conflict was not used. Hybrid war.
Lately, I've been watching mostly BBC news on TV. Various sources from internet.
The BBC is honest enough in many of the reports to note "this information is not verified from independent source", which basically means they are quoting somebody elses press release.
The word that is not used frequently, and has not been used on forum, is "hybrid war", and in my opinion this conflict in Ukraina is the biggest hybrid war so far in history.
In hybrid war, propaganda, media warfare, cyber attacks, are important part, as important as irregular troops, high tech equipment, and other means.
Diplomatic activity is at all levels.
Diplomatic talks started next day after the conflict started. (which is highly unusual for a "classic" war)
When a military changes the focus from killing combatants to killing civilians - that side looses, you mentioned. Unfortunately not always. Will give two examples.
When the bad guys loose:
The last time when this determining of civilian killing oriented strategy was relatively easy.
It was in ww2: when Nazi Germany imposed racial laws, legalized and established concentration camps, and made the genocide, with concentration camps as industrialized death factories. On eastern front, since as early as 1940 (I beleive) they introduced order by Wermacht High command; for one dead German soldier, 100 locals will be shot, and for one wounded german, 50 locals to be shot.
So, this was the war strategy of Nazi. They lost. For free world, it was easy to make decision between right or wrong.
Then after the war, Nazi war criminals were on trial at Nurnberg, most of them found guilty: shot, hanged, and few got long term sentence.
Nazis lost the war.
However, the history records that Nazis are not the first to invent concentration camps.
When the bad guys win:
Concentration camps are actually first invented by Brits in Boer war; 1899 - 1902. under command of Lord Kitchener.
When conventional English troops, were not able to get upper hand in conflict in situation where Dutch were successful in using guerrilla tactics, they created concentration camps and collected there non-combatant dutch family members of Boer fighters, who were then massively dying of poor conditions, starvation and illness in the camps. Today, this would be recognized as clear genocide.
Loosing their families in numbers, the dutch surrendered, to prevent further genocide of their own people. Brits won the war. But obviously not, with honor.
So, winning the war, is not always about justice.
Fast forward 100 years plus, ahead to modern time.
Unfortunately, killing of civilians in XX century war is the thing that happens, either with intention or by accident, and it cannot be justified, and I can not find any XX and XXI century war without civilian casualty.
That is true humanitarian disaster of every modern warfare.
I've seen it in my country.
And this is now happening there, in Ukraine.
Moreover, unfortunate casualties are then used as opposing side propaganda in modern hybrid war, numbers reduced, or increased as per need to support each side war effort, or political gains after the war.
When the guns get silent, and the war smoke clears:
there will be a call for justice, and call for trial of war criminals. And probably it will be high profile cases.
For the purpose of serving the justice to war criminals, international criminal court was established, and started in 2002, after signing the Rome Statute with enough member states.
Now, there is 123 member states of ICC, Rome statute. (out of 195 world countries)
The countries that are NOT members of Rome statute are;
Russian Federation
Ukraina
United states
China
India
etc
(some are biggest countries in the world, some of them are in this conflict)

So, most probably civilian casualties in this conflict will remain debated, disputed, and never processed at international Criminal court after the war.
True humanitarian disaster.
We always tried to keep those guys at several arms lengths. The original tin foil brigades. This one is Air Force as well ..... !? 
I do believe he will be largely ignored. I'm sure he's having spotlight withdrawal.
