One of the early CNN commentators said as much from the border, until she got smacked.
I mean compare this to the (wholly preventable) starving of Yemeni children who get close to zero coverage because too far, too brown, too unlike us, who knows why these brown people insist on killing each other, let them sort it out. Even though the starving and the killing is fueled by American technology and intelligence.
Ukrainians also have the advantage of being close to perfect victims. The world has a problem with feeling sympathy for the imperfect. Look at the coverage of the Palestinians. So much of the discourse around it brings back their links to Hezbollah, their hostility to the gays, their treatment of women, their corruption, and much of it is true, but the subtext is - see, these people deserve it. They had it coming. They should stay oppressed. I've never encountered any commentary that said - look, imperfect people, too, deserve to be free of oppression. Freedom and human rights isn't some graduation prize awarded by the big man only when you meet certain benchmarks. Idiots and assholes, too, have rights.
But Ukrainians haven't really done anything wrong, and they are much more sympathetic than, say, Palestinians, or little brown Yemeni children. It's easy.
