Joe Biden plans to open a consulate in Jerusalem. This amounts to an actual US embassy to the Palestinians on Israeli territory. Many believe its true purpose is to undermine Israeli sovereignty in its own capital city. It will also jeopardise future prospects for peace between Israel and Palestinian Arabs. As well as betraying Israel, Biden's diplomatic signalling also appeases his hard-left supporters and is a betrayal of the Palestinian people. They have suffered too long and too hard under the hostility of their leadership, which has consistently refused to entertain all proposals for peace with Israel that could lead to the establishment of their own state. Successive Palestinian leaders have been encouraged in their inflexibility by the US and Europe, who have for decades extracted concession after concession from Israel while Palestinians make none. The intended consulate in Israel's capital will encourage greater support for Hamas, currently ruling Gaza.
