One of the reasons the U.S. has problems dealing with the Eastern mind is our continued failure to think like they do. We assume that since our thought pattern makes sense to us that it should make sense to a Russian. This is not the case. The Russians do not follow the Western tradition of philosophy and what has value in Western culture does not necessarily have value in the mind of a Russian. For example: Biden will place sanctions on Russian Oligarchs (by which he means very wealthy Russians.) He does this because in the Western canon of political thought money is power and the oligarchs will then force Putin to remove his forces from Ukraine.
But this, like most U.S. negotiating positions, is wrong. In the Eastern philosophy from which Russian thought derives, money is not power rather might makes right. You might be the wealthiest person in Russia but you are there because I, he who is in charge of the Military, Police, Tax authorities, etc, permit you to be. If you resist me I will arrange to have you discredited, investigated, arrested or perhaps you will need to meet with an untimely accident. The supposed oligarchs of Russia do not control Putin as U.S. politicians may be controlled by money, rather he permits the oligarchs to exist.
In Russia might makes right and might will have its way. Biden arrives at this juncture because Obama failed in 2014 in his toe to toe joust with Putin and, secondly, because of Afghanistan. In 2014 Obama drew a red line in the sand of Syria and promised dire consequences should the Syrians use chemical weapons again. They did and he did nothing. Seeing this Putin realized Obama was a weak leader and not long after the Syrians chemical weapons usage he sent forces into Crimea to aid the Ukrainian resistance in its fight for independence from Ukraine. See a pattern? Biden bungles Afghanistan being willing to suffer all sorts of ignominy just to get out of the problem. Putin now knows that Biden, like Obama, is not a strong leader and does not care about the international reputation of promises made by the U.S. government and he begins to maneuver to take the rest of Ukraine knowing exactly how the U.S. will respond.
The East plays a long game, the West a short game, the East values life less than the West, the East has a much greater ability to rationalize than the West, the East believes might makes right, the West believes money talks louder than principle or resolve. The East defines peace differently than the West because the West believes peace grows out of a society wherein everybody is a participant, while the East defines peace simply as the absence of conflict, unless conflict is needed to keep the peace.
Lastly the West has many players each of whom must answer to other politicians. In this case the other side is one person, Vladimir III, Czar of all the Russians and according to him there are lots of Russians in Ukraine.
Prediction: After the Ukraine is pacified and happily part of Russia, Putin will turn his attention to the Baltic States where lots of Russian speakers reside.
