Niggas I don't understand why you are discussing the morality or righteousness of this war.
A huge mass of oil and gas was discovered in the maritime space of Ukraine close to the Crimea. In itself, competition for oil and gas for Russia is not pleasant, even against a neutral state, but after 2014, the constitution of Ukraine spelled out the intention to join NATO and the EU. For the sake of cheap energy, huge investments would be made in Ukraine, as they are now. So we are talking not only and not so much about the military expansion of NATO as about the economic one, and when Ukraine became part of NATO/EU, Russia absolutely could not do anything because everyone would start waving Article 5. So the bear has to stumble and do something now or starve to death in 10 years.
Nazism, globalhomo, freedom, and democracy are just reasons for soldiers to go to die and kill for oil. Would you agree that an additional 10 cents per barrel of oil does not sound very heroic?
