“What is the need for making up secondary reasons?”
Syag, Gedolei Yisroel, including Rav Eliashev, have explicitly and repeatedly cited antagonization resulting in anti-Jewish violence as one of the reasons it is forbidden to go up to the HH”B.
“Five years ago on Sukkos, President Shimon Peres paid a visit to the Sukka of Maran HaGaon Rav Elyashiv ZATZAL, where Rav Elyashiv called on the President to prevent Jews from visiting Har Habayis, stating it is an act that that is viewed as extremely provocative by the goyim. Maran stated everything possible must be done to avoid a religious war, and the provocateurs are playing with fire.
Maran is quoted as explaining to the president that Halacha forbids going onto Har Habayis but today, it is more than this, it is an act that may lead to a religious war and bloodshed.”
