People of Ukraine are extremely brave. Russians on the other hand are fucking cowards. I'm not talking Russian soldiers. I'm talking general public. It's they who should fight this dictatorship, not Ukrainians.
1. We do what we can. Since 2008 when 100+K people went out to protest the regime has significantly increased sanctions and arrests. You'd need someone on the top making a major move against the regime in this situation.
2. War in Ukraine is not just a one-sided affair. There are real issues that were not solved properly and it's a failure of diplomacy on many levels both on Russia and the West.
Russia should not prevent a neighbouring country from aspiring to be with EU and nothing justifies needless war.
However Ukrainian government has a lot of blame to bear. Ukraine as a country with 1/3 of Russian-speakers and Russian military bases decided to join Nato and ban Russian culture completely across the whole territory (language, books etc). Cutting water to Crimea is an interesting way of getting the peninsula population on your side.
Let's face it - the country is deeply divided along the Dniepr and Maidan was not just a revolution of Dignity - it was a shift of power from pro-Russian side to anti-Russian side. In current climate with US sponsoring hardcore anti-Russian rhetoric and pumping money the result is what we see.
And nobody cares unfortunately about civilians - the only difference is that Ukraine is located Europe. When it's Syria, Iraq, China, Afghanistan - only NGOs care. The world just held Olympic games in a country where more civilians are being put in concentration camps than the affected population of Ukraine and civil liberties, propaganda and threat to neighbors are much more pronounced than anything Russia can do (apart from maybe nukes that nobody will ever fire).
So it's nice that the world came around one specific issue but it's all shit and all around sad.
