Read international law: the 1920 San Remo Treaty which gave the British the Mandate for Palestine awards all of what is now Israel, the West Bank, and Gaza Strip to the Jewish state. This supersedes all contradictory UN decisions under int. law. Israel therefore has every right to annex and build across Jerusalem and the West Bank. It has annexed eastern Jerusalem, therefore it is part of Israel.
