Unless he has managed to become “Tahor”, and is going to the Har ha-Bayis to offer a korban, he has no business being there. All he does is it rub it in the noses of the Yishmaelim that they were conquered by the Zionists, which just encourages them to make mischief.
When the Bayis is rebuilt, combined with the demographic impact of techiyas meissim, the Arabs will be sufficiently impressed to stand down (and all those who pride themselves on their well paying jobs in the Kenesset will be unemployed since Eretz Yisrael will finally be a Jewish medinah, and have no need for the Zionist politicians, including the self-proclaimed Chareidi members of the Kenesset).
