It is equally true that Ramadan frequently has been celebrated with an orgy of Muslim, especially Palestinian, violence. Ramadan is exploited as an excuse for ramped-up holy war against Israel.
Ben-Gvir was quoted as saying that Israel “cannot take chances and risks in allowing residents from the [Palestinian] Authority to enter Israel in any way.”
Virtually all (Zionist) rabbis agree that the blessing must be said on the Hallel of Jerusalem Day, for that event came purely “min hashamayim,” from heaven itself, a precious gift from God.
However critical you are of Israeli policies, or however much you don’t like Ben-Gvir, Jewish presence on the Temple Mount isn’t the problem; the violence from the other side is.
