Hmm... For a more realistic answer not necessarily. This isn't the first time they invaded Lebanon. I'm admittedly not aware of why they left the first time, but from what I know at least in the short term they're mostly content with the territory they currently control. Of course "currently control" including Gaza, the West Bank and the Golan heights; ethnically cleansing those was always the plan. Also when Egypt inevitably collapses as a state I could see them trying to go for Sinai.
This isn't just an article about a little girl being sexually assaulted; it's an article about a little girl being sexually assaulted and the effect of that on French politics. People saying "but there's a genocide in Gaza" are concerned about the latter half here.
It's not far fetched to see antisemitism being an issue and think "they're gonna come after the anti-zionists too". This comes up in the article. This isn't "all lives matter".
No, now they're going to actually go to war instead of bombing defenseless children. The other front would be Egypt if Sisi hadn't sold his soul to Uncle Sam.
Muslims do not worship Muhammed, at all. Shia do have a weird obsession with his family that can reach worship according to my knowledge as a Sunni Muslim, but no serious sect of Islam worships Muhammed. "We don't worship our prophet, unlike what the Christians did to Jesus" is an important part of Islamic identity.
