I disregard any source that claims to know what Putin was thinking and his motivations.
It is a good point.
However, what Putin wants, and what Putin gets, may be significantly different things.
It has been alleged "The West" whatever that entity maybe, has cautioned Ukraine against using weapons supplied by "The West" outside of Ukrainian territory.
That appears to be true.
Russia appears, by attacking Ukrainian infrastructure, to be undermining that restraint.
It is certainly a dangerous time for all.
These conflicts can escalate far beyond what any side wanted to start with.
World War I is a prime example.
