Ukraine has done nothing BUT threaten its neighbors as long as it has existed, that was the point of the 2014 coup and the prospective membership in NATO, for it to be a launching ground into the heart of Russia.
That's some pretty seriously messed up propaganda you're spewing there. In the entire history of NATO, it has engaged in non-defensive, non-peacekeeping wars how many times again? And you think it is going to suddenly start now because...
The Donbass had declared its independence and had resisted invasion from Ukraine for eight years before they finally requested assistance from Moscow
Horseshit. Russia sent people into the Donbas to rile them up and stoke anti-government sentiment after Ukraine's previous Russian puppet leader got ousted. Russia provided money and weapons for paramilitary groups (otherwise known as "state-sponsored terrorists") to rise up against the government of Ukraine and divide the country.
The Donbas region had not done anything to separate from Ukraine even one day before they requested assistance from Moscow. Russia funded and supported the DPR and LPR secession attempt from the very beginning.
the far right militias which were leading the invasion openly declared that their aims were to "cleanse" the territory of ethnic Russians (the majority in the region) and replace them with "pure" Ukrainians (just read some of their literature).
What invasion? It was their country. The closest thing that region had to invaders were the Russia-backed terrorists who took over part of the country. They were a fringe group that took control of the territory at gunpoint and caused most of the population to flee. Were some of the people fighting for a right of return for those refugees bad people? Maybe. Do I care? No.
There's a right way to secede in the modern era, and it isn't with a violent overthrow of the government. See Brexit for an example. As far as I'm concerned, anyone who took money and/or weapons from a foreign government and used them to overthrow their own government gave up any claim to moral high ground long ago.
If "Putin's aim is genocide" then he's the most incompetent barbarian ever,
You said it, not me.
between the two combatants the death toll among civilians after three years of war is still lower than the death toll of civilians in Gaza in the first month.
Only because Ukraine wiped out all of Russia's tanks right off the bat, shot down a large percentage of their missiles and drones, etc. Russia had more soldiers, but their technology is so far behind that Ukraine has basically been holding them back with a relatively tiny force, and at this point, Russia has lost so many troops that they're having to borrow some from other countries in bulk just to keep the war going.
Russia hasn't killed many civilians because they have basically lost rather badly, despite dogged determination to turn it into a win, no matter how pyrrhic.
If the US were actually interested in stopping a country from attacking its neighbors, firing weapons into innocent third countries, using WMD against civilians, and committing genocide then we'd be invading Israel today rather than shipping them all the weapons we can produce.
The U.S. should have done that a long time ago, IMO. There should have been a U.N. peacekeeping force in Gaza and the West Bank for the last thirty years, and then we wouldn't be dealing with any of this s**t over there.
But although the best time to do that would have been decades ago, the second best time is now. It's not too late to fix that mistake.
