Both women are extremely talented. I wouldn't deny that. Awad doesn't look Arab, but If I'm not mistaken, I caught on one of the TV promos that her mother is Bulgarian.
Israel's latest way of choosing its entry to Eurovision is for a "committee" to choose the performer/s and then the performer/s present/s a choice of songs on TV for live voting. This year everything about the choice was political to paint us as lovey-dovey Left, and that includes the songs themselves. Nini and Awad, apparently, were involved in the writing.
The last time Israel won Eurovision was when the formerly male Dana International represented us. Let me suffice to say that when I taught my male Israeli students high school EFL students the linguistic meaning of "it," they understood perfectly when I used that performer as an example.
There are lots of youtubes of Achinoam Nini and Mira Awad singing; I took this one from Israellycool.
