It's not that this is good or acceptable, but if you're just now getting mad, or just now seeing humans for what they're truly like, then perhaps this is a good lesson and an important milestone in the maturation process. Human nature has not changed so much over the last 80 years. It's good to be reminded of that, though the reminders are difficult.
People in countries around Syria talked about war in Syria a lot. And in that conflict, America seems to be blamed for both intervening and not intervening enough. It is guilty of Russia bombing cities and Assad actions ... and also for helping rebels in actual fight. Because, in relation with Ukraine war, it is important to make America guilty of literally every bad thing everyone does in every conflict.
Maybe projecting nihilism is a strategy of its own. If I act as if there is nothing I care about except my goal you will never convince me to give up. So you have to give up to spare casualties.
If Russia really did go to war over securing some natural resources and a geopolitical strategic location, over a false pretense of something like liberation, it would sound so much like...well, us.
So let us take a quick moment of pause and realize that this demon lives well within our own borders, too.
Hoping and praying for peace.
