In the decades-long Palestinian struggle for self-determination, one issue towers above the rest: the fate of Arab East Jerusalem, with the Old City at its heart. Israel swiftly annexed East Jerusalem following the 1967 occupation, declaring it the unified, eternal capital of the Jewish people. Yet annexation failed to resolve Israel’s core challenge: demographics. Palestinians formed the vast majority in the Old City and surrounding Arab neighborhoods, with their population within Jerusalem’s municipal borders growing from 68,000 in 1967 to about 330,000 by 2016.
