I've just finished watching the film about the Kursk. It's a dramatisation so obviously there are some factual errors/poetic license.
However having looked at other sources, the premise of the movie, that a mixture of national pride, military incompetence, poorly maintained equipment and an unwillingness to provide realistic assessments of the situation to Moscow was the cause of the failure to rescue the submariners who survived the initial explosion; men who could have otherwise survived.
In Russia the cause of the tragedy and the inept response to it was whitewashed by state media and support for Putin remained.
In that context it's no surprise that we are seeing the same again.
In reference to a post by RTB above, the reports from Kharkiv (where a substantial proportion of the population is Russian speaking) that there is now a fierce backlash against the Russian people is understandable in the context that many have had relatives in Russia respond to their experiences of being shelled as fake news or that the attacks were made by Ukrainian Nazi's.
They are angry at seeing an entire country closing their eyes as to what is happening.
For my part I cannot conceive that the majority of Russians buy into "a special operation". They know what's happening. The same way the majority of the German population knew what was happening to their Jewish friends and neighbours in WW2.
They are simply making a choice to buy into the rhetoric of the state and unlike the Ukrainians lack the will to find their own voice because the path of least resistance is the easiest.
We too in the West have lacked "will" in the 20 years since Putin became President. We've tried to charm and appease him without understanding that the only characteristic he values is strength.
I don't think peace talks will be effective because Putin isn't operating in good faith.
That said I don't think we are at the brink of a nuclear engagement.
Rather I believe we will see a long war of attrition where who ultimately prevails will depend on the West's ability to avoid compassion fatigue and the impact of economic sanctions on our economies to keep supplying Ukraine with the wherewithal to defeat Russian forces.
