Now back to the real subject of this thread:
You are so right on that one Rod. It has been the case in almost, if not all, the wars of the twentieth century and is still the case now. The propaganda made by all sides with the downing of Malaysia Airlines Flight 17 (MH17/MAS17) over the Ukrains / Russian border is a 21st century example. Now Syrian civilians are being used as the propaganda pawns around Mosul. The propaganda nowadays spreads to the internet for extra impact. This is a good example of it:
www.iamsyria.org/death-tolls.html
So 525,000 killed, including 55,000 children, and look who they are blaming. What is THE truth though. We shall not know, if other conflicts are a guide, until the history is researched in years to come.
Can this situation ever change whilst conflict goes on? I doubt it.

Not only propaganda but also Russian 'agitprop' or 'active measures' along with cyber-warfare. The Russians are currently by far the best in the world at this and where I follow the Russian invasion and war closely in Ukraine, I have learn't much and also to a lessor extent from Syria. The Ukrainians have been subject to the full suit of these Russian tactics. Everything from funding fridge nationalist parties, paying people to cause problems (that went badly wrong in Odessa), terrorist attacks including civilians in Kharkiv, 'wetwork' with the recent killing of a former Russian MP in Kyiv an example, not to mention cyber attacks which have shutdown a power station and sections of their national grid twice. They have also deployed a full suit of economic measures, which range from confiscating Ukrainian factories on Russian soil, to banning the import of most Ukrainian produce to literally using their 'aid white lorries' to dismantle whole factories in the Donbas and exporting them to Russia.
This is an example of their current 'active measures':
https://jamestown.org/program/russian-disinformation-pervades-central-eastern-europe/The other side of the coin is that Russia has failed on all of their political objectives since taking Crimea, with their invasion of the Donbas and trying to break Ukraine economically and politically. Ukraine have switched to exporting much more to Europe and worldwide, so after a post-2014 sharp painful recession, their economy is now growing and the growth is accelerating.
Although their is still an active war being imposed on Ukraine by Russian with an average of one Ukrainian KIA and several WIA virtually everyday, this active engagement is far from one sided with Russia suffering (classed by them as secret) causalities as well. The Ukrainian SBU have also had their hacking successes with the Glazyev Tapes and Surkov leaks.

https://informnapalm.org/en/cyberwar-purges-in-russian-cybersecurity-could-be-connected-to-surkovleaks/I could just keep writing on this and other current things, like Russian 'active measures' to get Trump elected. There is much good information out there but also many disinformation 'fake news' websites, which means I tend to stick to top accredited academics, with most names start with 'Professor', proven journalists and people I have got to know over time and can I verify from multiple sources that what they say is factual.
NATO countries are closely studying the war in Ukraine and Syria to learn about modern Russian tactics and capabilities. Western post-1991 complacency is learning some hard lessons, hence the US urgent upgrade program to add reactive armour to M1 Abrams tanks. I suspect there is also an emergency TOW missile upgrade program as (Saudi supplied ones) have failed to penetrate T90 armour when used by the Free Syrian Army. UK Challenger tanks and munitions are also in urgent need of upgrading if they are going to be of any use in future conflicts.
