Very good point.
Lots of misinformation, propaganda and foolish analysis. Taking my time to wade through it to derive opinions that are sound. Very hard to do. At this point, about the most I can say is that Putin has lusted after Ukraine for a long time and he has been looking for an excuse to do it, like protecting Russians in eastern Ukraine. My personal opinion is that the following issues motivated him more than anything:
1- Biden moving to restrict US oil production, boosting oil prices
2- Pipeline running though Ukraine
3- Warm water seaports of Ukraine and Crimea are very much big issues for Russia, both with respect to trade and military use
4- Controlling agricultural production capacity in Ukraine
Simply stated,the Ukraine and Crimea are essential for Russia from a strategic standpoint
Oops. Forgot 5- potential NATO membership for Ukraine. Were I Putin, that would make me uncomfortable also
