There's a great post at cybercossack for anyone who doesn't understand Ukrainian animosity towards Russia.
It's a speech made a couple of years ago, but it is truly timeless. It outlines the cultural genocide of Ukraine throughout history, as well as in the context of 20th century Soviet-made famines and other murderous methods of annihilating Ukrainians... and also the west's complicity.
Pretty much illustrates why sovereignty is so important and precious, and necessary for Ukraine's survival... and why Ukraine historically has struggled alone and unaided.
Read it and weep. Here.
Then resolve to be part of the solution.
