everything right what you cite there.
But, with all the horrors of the images that stormed on us at the weekend, and there will be more guaranteed to follow.
The broken promise to Gorbachev at the fall of the Berlin Wall by US Baker, Genscher and other EU foreign ministers that there would be no NATO expansion to the east is part of the poisonous seed that Ukraine now has to atone for.
Ukraine cannot stand against Russia, no matter how you arm it, the suffering of the people will only increase.
Putin will not stop even if we cut off his gas from tomorrow.His warfare is ruble financed,food,oil for his army he has himself,the markets for it too(India,China),his countless,somewhat outdated tanks do not need western know how to inflict suffering on the population.
There will be either a two-state solution of Ukraine; the East and Crimea sympathizes with Russia anyway, the West with us. Or a completely neutral status, no EU accession, no NATO.
In addition, it needs startegic geopolitics that the security interests of the hostile great powers also more into the calculation draws.Even if we do not like it.
You can not defeat these forces, only through the 3rd World War,but then the lights go out everywhere
