Is President Putin a War Criminal or a Patriot?

Note this day: On February 24, 2022, President Putin of the Russian Federation sent in Russian troops to invade the sovereign country of Ukraine. Ukraine achieved its independence on August 24, 1991 after the fall of the Soviet Union. Putin, justifying his invasion of Ukraine citing Article 51, part 7 of the United Nations Charter, accused the Ukrainian government of "abuse and genocide" against the separatist regions in Ukraine of Donetsk People' Republic and Luhansk People's Republic. Ironically, it was the former Soviet Union that committed genocide against the Ukrainian people from 1932-1933 killing millions of Ukrainians. The Ukrainian term for the genocide was "Holodomor" which means "to kill by starvation". This was also known as the "Terror-Famine" or the "Great Famine". The United Nations estimated that approximately 7-10 million people perished.

Is Putin justified in this action? Is this a "just war"? Is Putin a Russian Patriot or a common war criminal. You decide. My mind is already made up.
