An Egyptian MP is urging that Muslims begin mass pilgrimages to Jerusalem in order to demonstrate "that Jerusalem is for Muslims". The MP hastily rejected the idea that this should be interpreted as normalizing relations with Israel, even though he did say that visitors should even get Israeli visas, if that's what it takes.
Jerusalem is a very important city in Islamic history and theology, and I don't want to deny that -- though I suspect that this MP would not reciprocate in acknowledging that Jerusalem is if anything more important in the Jewish tradition.* At the same time, I'm not sure one can claim legitimate rights to a place by ramping up its religious significance (or at least, making its significance more prominent) ex post facto. Can Jews do the same thing with Hebron? Jews make pilgrimages to New York City for bagels all the time -- can we claim it as a "Jewish city"?
* Simply because Jerusalem is Judaism's holiest city, whereas it ranks third in Islam behind Mecca and Medina.
