Old video, seen it, has some more or less valid takes, but at the end of the day it's been Russia that attacked Ukraine.

And pundits and scholars about this being geopolitical chess games in eastern Europe are largely, albeit not completely, mistaken. This has always been about Putin's fear of democracy in Russia and him losing the grip in his own country. It is no coincidence that Russia attacked Ukraine a month after the unrest in Kazakhstan[1], few weeks after Russian military helped crush it.
