I don’t disagree with all your points nor with the isolated points of the video, but that’s basically trees you see and not the forest. The capital restrictions you are mentioning are pretty mild by world standards and they have saved investors tons of money in hindsight. You are also heavily overestimating the need for foreign investment for Russia which proved to be a rather self-sustained entity.
Last but not least, I generally estimated the Russian conventional military as weaker compared to NATO. Now my opinion has changed. I understand that the NATO involvement is rather limited but judging their weapon systems and tactics I think Russia is currently not that far behind the old USSR in countering it and perfectly capable to sustain a large campaign much better than NATO.
LOL, after 100 days of inept Russian offensive in Ukraine you still believe Russia is "capable to sustain a large campaign much better than NATO"? Okay
