Displaced Lebanese cannot return to southern Lebanon because of Israel's documented use of white phosphorus in the villages of Nabatieh, Tyre, Khiam, and Yohmor. With fresh evacuation orders and over 1 million people displaced, residents of southern Lebanon have nowhere to go.
It would be embarrassing to Israel since they deny using it against the rules of the Geneva Convention.
What’s embarrassing is that the country trying to be a Jewish ethnostate is committing genocide. If that is not embarrassing enough, a violation of the Geneva convention definitely won’t be worse for them.
Both would be embarrassing but proving the illegal use of white phosphorus would be easier.
