Russia Ukraine war, page-201940

"... but its a bit hard to avoid major collateral damage when they are jammed in like sardines with Hamas..."
It's really easy. Don't shoot missiles/bomb areas where civilians live. Don't tell the civilians to get out of wherever they live and go to a designated location - and then bomb that "designated location".

You're missing one point. The whole Gaza operation is not about Hamas. It's about ethnic cleansing. Not the "Final Solution" type of cleansing of course, but it is nevertheless a part of the wider Israeli campaign to drive the Palestinians out of their lands.

"...Russian missiles and drones have been deliberately targeting Ukrainian hospitals, schools, kindergartens, railway stations..."
You do realize that the Ukrainians have adopted terrorist tactics, and are stashing ammo, hiding troops, weapons and equipment in all of the locations that you've mentioned? Read up on it. ISIS used to do the same type of thing all the time... Both ISIS and the AFU learned from the same manual. Written by US of couse.
If you did any research, you would have come across plenty of videos of the AFU (Armed Forces of Ukraine) concealing their equipment/ammo/troops in all of the locations that you've mentioned.

"...it had to be deliberate especially since the timing of the attacks just happened to be when the targets were crowded..."
Please provide an example.

"...If it wasn't for the excellent work by the Ukrainian defences most of the populated areas in the eastern half of the country would have been blown apart by now ..."
The Russian AF dropped close to 100 FAB's on Avdiivka within a space of just a few hours the other day. Avdiivka is almost completely evacuated by this point. If Russia was deliberately targetting civilians - they wouldn't have any major problems bombing, let's say, Kyiv right into dust. They wouldn't have had a problem of levelling Kherson, about the time when Zelensky was there. They wouldn't have had a problem absolutely annihilating whatever remains of Robotyne, while Zelensky was there. They didn't. Why?

"...the only possible reason being to terrify and kill civilians to break their sprit..."
Zelensky's government is already doing well enough at terrifying the civilians, by trying to impose draconian mobilisation measures. Pulling people off the street by force, trying to pass laws that would allow the Ukrainian government to confiscate property, freeze bank accounts and revoke passports of ordinary Ukrainians that refuse to go an die for Zelensky's puppet-masters.
