Today, no cities are truly internationalized under the sense of being under the jurisdiction of multiple states or under the sole control of an organization (i.e, UN headquarters is controlled by the UN, or only the OIC has jurisdiction over Mecca)
What cities could potentially be internationalized to a certain degree? Hear are some of my ideas:
1. Constantinople: Russian and Ottoman collapses during World War I leave the city vulnerable to the Entente. Giving it to Greece, Bulgaria, or the nascent Turks will pretty much guarantee a shooting war sooner rather than later so the Entente turns it into the League of Nation's Capital
2. Jerusalem: Direct UN administration before the creation of the State of Israel (with protection of the city under joint Israeli, Islamic, UN, and Christian control)
3. Danzig/Gdansk: Whatever German entity ends up controlling the country after World War I agrees to joint control of Danzig with Poland in exchange for an alliance
4. Mecca/Medina: Probably need to do something about the Saudis and the Hashemites for this one. UN administration with an international task force comprised of Muslims from multiple countries?
