Earlier quoted context omitted.
Contrary to what you're insinuating, this is one of the clearest cases in recorded history of conflicts. Russia is the aggressor and started a territorial war against Ukraine - already in 2014, now turned into a full-scale invasion. You need to check your moral compass and brush up your knowledge of international relations and history.
Not true. This has been eight years in the making. Civil War at Russia's borders. A fascist, neo-Nazi military terrorizing ethnic Russians. 14,000 dead in Donbas. Your "clear case" is missing quite a bit of information.
Nice try but the exact opposite is true. During the past 8 years, those ethnic Russians have been snatching other random ethnic Russians from the streets in the Donbas region to torture them for days to weeks. They're no more than a bunch of Kremlin-controlled thugs. There are plenty of eye witness reports to corroborate the horrendous human rights violations in the Donbas region by their self-proclaimed governors and their goons - and they are radical Russian nationalists aka Neo-Nazis.
