We're discussing Rusia - an expansionist, fascist nation lead by a dictator, who, if possible, would invade your country and put it under complete Russian control.
And while we're at it - what "legitimate security concerns" does Russia have with respect to invasion of Ukraine?
Oh, my bad, a NATO nation on its borders is intolerable, clearly Russia is in the right to inv...
Hold on? Do other NATO nations border Russia? If so, how is it that Ukrainian membership in NATO is a new threat to Russia to the extent that it must invade Ukraine? Or is the potential NATO membership of Ukraine just another excuse to invade a neighbor to expand territorial dominance (hint - it is)?
Clue - Russia keeps on changing its story about why it's invading Ukraine. The story started out along the lines of wiping out make-believe Ukrainian Nazi's who were targetting Russian loyalists - next some sort of tradition holds that Ukraine belongs to Russia and the vast majority of Ukrainian citizens welcome Russian membership and so Russia must act to prevent Ukrainian autonomy as this is against the will of its people... and so and and so on... lie after lie.
