I don't support either parties in regards to a war, because the reason for this or any other war in the past 10000 years has never been different. And I am also neither Ukrainian nor Russian.
It has always been about certain parties $/economic interests (those of the elites in a society) against other certain elite parties $/economic interests.
If the common people oppose those elites - the latter usually represented via a government, it isn't called a war but civil unrest or revolution. Just as the revolution in the American colonies - (elites or wanna be elites) amongst the colonist, contra the established elites of Great Britain. Upon declaring a government run by colonist elites - it was termed as a war.
The common people are told and made to believe, since 10,000 years it's all about, democracy, freedom, religious or ethnic/cultural righteousness. Or e.g. my personal favorite, someone's beautiful wife was taken to Troy and marital matters needed to be set straight accordingly.
Since 1900 the USA has become the leading nation in this drive for $/economic dominance. After WW2 the only remaining rival was the Soviet-union countering via communism.
The Soviet-Union ceased to exist in 1991 and the Western world's general population was convinced that now Russia won't pose any serious thread towards a war - after all they had gone bankrupt and as such couldn't pose a danger towards the US/EU $/economic dominance, and for sure those Russians will be damn happy and grateful to finally become a member in this US/EU lead world economy. Ahhh... in this democratic and freedom minded world.
Countries that behold an autocratic political systems are hard or even impossible for the Western democratic economies to break into or to convert them. As such a total global dominance by the US/EU propagated/favored system is still not in sight.
Since communism proved to be an economic/social failure - almost all previous communist or socialist states became autocratic countries practicing capitalism.
Russia and e.g. China manged to get/regain a grip onto their economies - via an autocratic/capitalist system - and therefore made things again harder for the US/EU lead economic expansionists who's primary tools are based onto the democratic system. (and respective damn democratic oppositions and mean sniffling journalists are really a headache or even an impregnable barrier at times) NATO or the US Armed Forces are simply an extended means of pressing US/EU economic interests towards such opposition via a military backed solution/option. Therefore a Ukraine being a future NATO and EU member - will place a huge obstacle towards Russia's Ruble/economic interests, might even break their back.
In order to protect or expand Russian Ruble/economic interests - Putin can't allow for a further NATO/EU eastward expansion. Either Ukraine can be politically controlled by Moscow or at minimum settles with neutrality - if not, a war might offer a preliminary solution or even a final solution.
Right now I can't recall a single war since the Soviet Union ceased to exist, that wasn't based on a US/EU economic expansion or maintaining a status quo that was opposed/hindered by a country/leader maintaining an autocratic capitalist system.
Only money rules this world - nothing else.
