No clue about military strategy, but I always find it off-putting to leave out the dramatic humanitarian, moral, and legal violations that Russia affects on civilians. To me, you can't talk military strategy without mentioning that the whole war has been an incredible crime and violation of the foundational values of western societies as well as the corresponding international laws.

[edit]: Uh, it doesn't help this stream's credibility that the guest is a convicted sex offender and pro-russian commentator. From Wikipedia:
"Ritter is a registered sex offender, having been convicted of unlawful contact with a minor and five other charges in a 2011 trial.[2]"
"Ritter has regularly written op-eds for Russian state-controlled RT, such as about the 2022 Russian invasion of Ukraine."
