I have yet to figure out a valid reason as to why Putin even started this war.
Pootin uses the excuse that it is for Russia's security, but in truth it's a land grab and the theft of Ukrainian resourses. The Donbas is rich with industry and resources, and that's what Pootin is after. There is no valid reason, it's greed... and millions have suffered for it.
The invasion itself is an atrocity and a war crime.... and further atrocities continue wherever the Russians go in Ukraine. Stalin was Russia's first butcher, Pootin is the second and most certainly a war criminal.
