And it's not just Ukraine - what about Sri Lanka which is collapsing by the minute? I do care about the people, but if I am completely honest, I could care less about the government. If the current government can fend off Russia, great, but maybe (I don't know for sure) it would be better for the people for some sort of diplomatic solution to be created (perhaps surrender a part of Ukraine but allow anyone interested to leave the new Russia peacefully), that might be better for people on the ground than an endless war. Surrender for now for the sake of stability, but regroup and don't allow such a thing to ever happen again and take some lessons learned from this.
I'm not inclined to see American-backed separatist movements as entirely "internal" either, but Ukraine is not as homogeneous as some would have you believe.
