The idea that Putin plans assassination of Zelensky seems extremely farfetched because even as a year has passed, there are essentially zero known operations with goals that are even close to that.
It is interesting to me that many American nationalists (and some others) seem to be operating under the assumption that Putin is an idiot in terms of mental capacity. That would have the unfortunate implication that the combined economical warfare of NATO was unable to stop a much smaller economy built by an actual honest to god retard, that is incapable of distinguishing basic facts in a ground war and lives in constant delusion.
If NATO really would run a draw with a mentally disabled man like that, then it would mean they truly are the most paper of tigers.
Instead, I would assume that NATO has a higher degree of competency, and so does Putin. Tabloid assertations that Putin expected Ukraine to surrender in 3 days and had no backup plans are not only disrespectful of Putin's intelligence, but disrespectful of the intelligence of all the officials in Washington, Warsaw and Berlin, who are stalemated with the system built by "the idiot".
When we assume rationality, the goals and methods of Russia become clear.
Russia initiated its invasion to prevent Ukraine from reunifying the LDPR after building up its army, seeing that the Minsk agreements were a sham, a statement supported both by Russian and NATO claims.
Russian troops did a whole song and dance for the world in the Kiev and Sumy regions, while that happened, they secured the land bridge and started fortifying the LDPR, ensuring that Ukrainian reunification will not happen for the foreseeable future.
As we see now in Bakhmut, if the Ukranians dig in, it will take extreme time for Russians to get them out using smaller forces. However, that did not happen for any settlement in the land bridge. Needless to say, if there was a Bakhmut in the land bridge, then Russia would have to fully mobilize in order to save Crimea, because they would otherwise be overwhelmed by sheer numbers.
The Russian army is not very powerful, but it is rather aware of its own limitations. It has used sparing amounts of assets to sneak vast tracts of defensible ground from a numerically larger foe.
From there on, it's now down to positional battles and which side can grind the other down first.
For those expecting Russia to have blitzed Ukraine, that was simply not an option. Not only is the difference in numbers and stockpiles not large enough to make a blitz a forgone conclusion, but there is the constant threat of nato intervention.
Ground lost can be taken back, men lost won't grow back.
The US army once blitzed through North Korea in 2 months, only to promptly lose all their territorial gain and have divisions straight up annihilated in 1 month when China intervened.
If Russia followed the same template of taking vast swathes of Ukraine only to get bitch slapped by NATO PVA (and they would, because NATO has turned back every promise theyve made so far), Russia or at least the LDPR would not survive that.
However, if Russia depletes Ukraine of soldiers first, there will be no one to resist LDPR independence.
This also explains why US did the warnings they did. They did not want Russia to invade because doing so ruins the plan for Ukraine to use Minsk as a smokescreen to acquire unification capabilities. Washington tried to discourage it by saying "we know your next step", but evidently Russia did not care and went with it anyways.
