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.
I mean, not just Starmers. Your point stands for a whole lot of governments.
