Actually it's hundreds, maybe a 1000 according to some, mostly Alawites, and probably a few Christians as well.
Highly doubtful that Israel is the only country to say anything given that Alawites were why Iran was there in the first place during the Civil War. Alawites, as you already know, are a small Shiite sect. Hence the connection and pact between Assad and Iran.
Funny, I don't recall any of your or anybody else's memes on the subject of Syrian atrocities prior to this convenient insta whataboutism used as a counter to criticism against Israel. Because if it wasn't for the genocide of Palestinians committed by Israel - which includes Muslims and Christians - nobofy would have noticed.
Other than Iran.
