So far (other than Shrubber, who did provide some argument about the Hiroshima and Nagasaki, no matter the disagreement between us), all other lefty Yankees don't go any further than "Putin egomaniac", "oligarch evil", "all Russians should go to hell" etc. Not to mention how rude they are in their communication with those who think differently. It's hard for me to believe that your brains are that heavily polluted by media and propaganda that you fail to perceive the facts objectively and unemotionally.
No, Russia didn't attack Ukraine because Putin is an evil egomaniac (he might be, but that is completely irrelevant). And no, it's not to reinstate some medieval Russian empire. And no, it's not a complex matter, but a very simple, geopolitical one instead.
As you hopefully know, NATO was formed after WWII to compete against USSR during the cold War. Few years later, Soviet reaction to it was forming of the Warsaw Pact. Warsaw Pact was a buffer zone between USSR and NATO, and it consisted of several central and eastern European countries plus Albania from the south, thus making the "iron curtain".
Now, a big part of this conflict lies in the fact that NATO has violated the agreement made by James A. Baker and Mikhail Gorbachev in 1900, - that NATO would not extend past the territory of then East Germany. That was an assurance made by NATO on many occasions after that. NATO starter expanding as soon as 1999 when Poland, Czechia and Hungary entered, and continued in 2004 with East Balkans and Baltic admissions. By 2009, my country enters the pact. You might wonder why didn't Russia stop the the countries, namely Baltic ones (closes to Russia) to enter NATO? Well, Russia was experiencing its worst time economically since wwii during drunken buddy Yeltsin rule, and the country was by no means capable of opposing it. Only in late 2000s did the country start to consolidate and grow strong enough to start planning what we're witnessing these days.
What is interesting is that we're experiencing similar pattern seen in many countries with big Russian minority:
1. People live in relative or absolute peace.
2. Current government at the time, starts undertaking steps towards NATO.
3. Naturally, Russian minorities oppose by secession from those countries by forming their quasi, semi-independ states (Abkhazia and South Ossetia broke up with Georgia that way, Transistria happened in Moldova).
And now point 3 is happening again, in Ukraine.
After the 2004 Orange Revolution, there was a re-run of the elections that initially sparked the protests, in which the pro west Yushchenko, finally wins in the west, namely in Lviv (5.5%), while his opponent, pro Russian Yanukovych, gets a major win in, you guessed it, Donetsk (10. 1%). Victor Yushchenko gained ~5% more than in the first run and became the president of Ukraine. I'll stop writing about Orange Revolution, although whether it was or wasn't orchestrated by external factors makes it is an interesting topic itself.
At that time, Donetsk region started threatening to break away. However, the threats were quite mellow at the time. Only after Yanukovych finally got to power in 2010, and then got driven away again in 2014, Donetsk and Luhansk started expressing their scepticism toward the new Ukrainian government. Coincidentally or not, at the same time Crimea (which btw has always been showing very strong pro Russian sentiment) gets annexed by Russia.
Crimea is also a topic for itself, and the roots of the unrest there were purely economic (oil driven). That's a very pragmatic approach and a discovery in 2012 confirms that as it finds that west of the peninsula is among the areas with richest reserves in shale gas in Ukraine. Soon enough, exploration and drilling rights were granted to Exxon and Shell.
The other of the two richest deposits lies in, you guessed it, Donbas. It's self explanatory by now.
Is Russia breaking the international law by attacking a sovereign country? Yes. Is everybody against it? Yes, and rightly so. But it is apparently strong enough to do so. Might is right, unfortunately.
Do not forget that NATO (spoiler: double standards ahead) was the first one to make exactly the same breach of international law when it was bombing Serbia (my country's nemesis), which was also at the time defending its borders. Our neighbor's borders were then changed, which opened a Pandora's box worldwide.
Might is right, deal with it.
Maybe I'm blessed in this situation to come from a country that has, for most of its modern history, been neutral and nonaligned. Perhaps that strips me of any bias in this situation. And whether I fuck goats or not, these are all relevant facts which can be checked easily.
