Putin is a statesman who inaugurates statues of Alexander III once every few years in Russia. The Tsar best known for anti-Semitic pogroms, Russification policies and tightening the screws on Russian society more and more in place of solving its fundamental problems and contradictions. Yet for all those things Alexander III was also known as a peaceful ruler, he didn't start one war or rise to any provocation.
Now, about what I think is going on
All the current maneuvers, including:
the huge build-up of Russian forces on the border
the return of Poroshenko to Kiev from Warsaw where he is busy demonstratively making an absolute mockery out of Zelensky and destroying whatever meager authority and control of the state he has left
US officials hysteria about Russia invading imminently
Some Ukrainian officials saying the opposite, that they see no threat of a Russian invasion at this time
Ukrainian tankers on exercises swapping the Ukrainian flag on their vehicles for that of the flag of the UPA (WW2 era Nazi collaborator organization)
Are all to do with a Ukrainian offensive on the Donbass, which is still on the cards, which is very much neccessary for NATO membership and official forces to be stationed on its territory. The Ukraine is being whispered to in one ear 'do it!', while Russia is outright saying 'don't do it', and not only to the Ukraine. The clown president, couldn't take the heat and last week began talking about it being time to return to the peace process and de-escalate things https://crimea.ria.ru/20220111/prishlo-vremya-zelenskiy-sdelal-gromkoe-zayavlenie-po-donbassu-1121998709.html
The words are not fundamentally different to what he has said before in previous months, but the difference is that he made the statement during a meeting with French and German advisers. The French and Germans had previously restated their commitment to the Minsk Peace Process, which Zelensky had tried to reject over the past year.
Aaand. Queue Poroshenko returning to Kiev 2 days ago from Poland.
Now what happens if Porky seizes power in the Ukraine and goes ahead with an assault on the Donbass? Well I don't think Russia will invade with all that hardware, the Russian political and military leadership just like to keep their adversaries guessing. In reality they know their judo and Sun Tzu perfectly well. But anything can happen. Some sponsored rebellions, some precision strikes, whatever. Neither Zelensky nor Poroshenko have any more than single-digit support in the Ukraine at the moment, but there aren't really any alternative political forces to sponsor there for Russia in any case, so outright destabilization will probably be a bridge too far as far as any Russian objectives go.
The other explanation is that the US and Russia have already agreed on the Ukraine, and that the rest of all this stuff is just theater. In that case they will have already agreed about where the new lines of contact will be. A similar deal was worked out between Turkey, the US and Russia (representing Syria) in north-east Syria in 2019. The US military moved out, self-destructing its bases in the region in the process, and the Turkish and Syrian militaries moved in on pre-agreed lines of contact, with the Turkish advance into a big strip of territory causing about 200,000 civilians to flee and become internal refugees.
Personally I view this explanation as less likely, mainly due to the fact that the US and Europe are dividing on the Ukraine issue now quite visibly, which they probably would not do if the US had already pre-agreed with Russia as France-Germany were always more the doves on the Ukrainian issue compared to the US.
Also, Russia really has no need for the Ukraine for the medium-term and won't be able to swallow and digest it along with all of its problems. I doubt Russia would be interested in occupying some half of it - it's objective is to prevent any NATO presence there.
The wildcard here is if Zelensky manages to hold on to power and avoid any offensives, possibly with the aid of the Europeans. The Germans have already gone to Moscow for some discussions.
