This is such a mess to unpack. I can't support a direct attack on civilians no matter how awful their government is. For that same reason I can't support a lot of things Israel does to civilians in Gaza. And that's before you get into the question of who allowed a music festival within walking distance of the border and who ordered the blatantly obvious stand down that occurred. Or for that matter how much of the whole thing was staged.
All that said, strategically I am very glad to have Russia and China taking the Palestinian side in this conflict because it suits our interests for them to be there.
