This is the only act that is worthy of the title WINNER imo. Nothing else makes an impression quite like this. It will win. I can't imagine or believe anything else..
Everybody watches Eurovision with a little bit of politics in the back of their mind, and when Ukraine comes on, the whole world will expect something out of the ordinary considering the country's situation, and the way it has been portrayed in the media in the past few years + knowing that they didn't participate last year. Jamala's delivery comes across as very heartfelt, and you can feel the despair in her and the song, which will tick all the right boxes. Everything else will seem banal and trivial in comparison to it.
In the end you can take what you want from the song. I don't think it's about the specific problem or the specific enemy, it's about conveying the unhappiness of it all. I also think it would have been even more out of place had they sent a typical euro-schlager, when we all know the state of the country.
