There isn't a single country on the planet that agrees with you.There is no such thing as "East Jerusalem". Jerusalem was divided only because of fierce fighting between the Israeli army and the Jordanian army (who had absolutely no legal right to it). The final status of Jerusalem is to be negotiated as part of the final agreement between Israel and a future State of Palestine.
There is no possible legal claim to be made that Jerusalem, in its entirety, is "not Israeli property". Anyone who argues that it ALREADY belongs to a State of Palestine or that it is Arab land has fallen into a web of deceit formed by Arabs and supported by an international community which makes up law in order to demonize Jews.
The Old City of Jerusalem contains the most sacred places of the Jewish people. It has been the focus of the Jewish people's faith and history for thousands of years. Israel is strong enough to keep it. And she will.
