The UN has now formally classified the situation in Gaza as genocide—but this designation is unlikely to change anything on the ground. Israel has long dismissed the UN's legitimacy, most graphically when it shredded the UN Charter at the General Assembly. The real question is whether individual states will now act on what the world has known for three years. In the UK, the US, and Germany, however, where pro-Israeli interests are deeply embedded in the political establishment, meaningful policy shifts remain highly unlikely.
