Today is Yom Yerushalayim, the 49th one since the miraculous day that the Master of the Universe smiled on our brave soldiers in 1967 and gave us the Old City which had been in enemy hands for almost twenty years. It has become a tradition to publicly celebrate this momentous event in Jewish history and some of the events include a march through the entire Old City by Jews intent on reminding all its inhabitants that they live now and forever under Jewish sovereignty.
Naturally there are some people who are upset by that. Of course it's all in the good spirit of post-Zionist, Western-culture-hatred that these concerns are raised. The same people who were barred from their holy sites for 19 years despite signed treaties guaranteeing them otherwise are not allowed to enjoy the fruits of their success. This is intolerable, and of course, racist.
Now remember that the Left is actual quite racist but they cloak it under the guise of political correctness. For Jews to talk about Jewish Israel is wrong. For benighted Arabs to talk about an Judenrein state of Palestine is fine, a natural reaction to "the occupation". So thus we have the Temple Mount, the Har haBayis, the site of the binding of our father, Yitzchak Avinu, a"h, but for them it's only one thing: the Dome of the Rock, a Muslim holy site. Jews need not visit. It'll just upset "the natives". And beyond that we have Yerushalayim, the centre of the Jewish world for 3500 years but hey, don't say that out loud. It'll just upset "the natives". We can't talk about how the Temple Mount is the centre of our nation but they can shout about their exclusive rights on all their loudspeakers and that's okay.
The linked article is especially weak, though, since its title implies there are two legal Jewish arguments against Jews demonstrating that Yerushalayim is a Jewish city, Old City and all, and nothing else. The first is taken from the Nevi'im and claims that the reason Babylon was punished for destroying Judah was because in addition to conquering our ancestors they humiliated us. From this the author learns the classic liberal lesson: you can win a war but don't you dare act like it. On most other days of the year there are multiple neighbourhoods in the Old City that Jews dare not tarry in or even enter. On Yom Yerushalayim, one day out of 365, we do and this is too much for the liberal mind. Sure we won a great victory, let's go somewhere else to celebrate. We don't want to remind "the natives" they lost or interrupt any of their "Soon we will slaughter the Jews!" speeches.
The second argument is even weaker, based on a statement that makes no sense. The author claims that the only time the word "degel" appears in Tanach is in Shir HaShirim. Unless her use of the word "Tanach" specially excludes Torah, she clearly hasn't read the first few sections of Bemidbar in which the word repeatedly appears. In that case the Degel is entirely about nationalistic identification since each tribe is assigned one so that everyone knows exactly where in the camp they are entitled to live. The degel, in fact, proves the opposite of her point. It is the degel of the State of Israel, the Jewish state of Israel, that flies over Yerushalayim. We should make no apologies for that and the locals should know exactly what the implications of it are.
All this goes without reminding folks that Islamic claims of Yerushalayim as a holy city are based on rumour and myth. The greatest proof is that even those that pray on the Temple Mount turn to face Saudi Arabia, the centre of their religion. They love the Temple Mount because it's important to us, not them.
We must understand, of course, that our Final Redemption is only in its earliest stages and that during this time we have to expect a certain level of imperfection in our Land. We are not at the point where we can simply expel all non-Jews who refuse to acknowledge Jewish sovereignty and enforce halacha as the law of the Land. Only the coming of Moshiach Tzidkeinu can help us achieve that and frankly, he's nowhere on the horizon right now. However, we can realize the this is the reason we share Yerushalayim with others, amongst them our enemies, not because it's a nice liberal politically correct, pro-diversity thing to do. The march is a reminder that although we cannot have our ideal situation we are still in a position to remind the others that God has given us through His kindness control of our Holy City.
