Whether to go to Israel or not is an old halachic discussion. The Aim Habanim Semacha, Rav Yisochor Teichtal ztz’l Hy’d held as the Yerushalmi in Maaser Sheni (5,2) quoted by the Tosfas Yom Tov there. We must go there to start building the Beis Hamikdash on which will descend the one of fire. This must happen before the coming of Meshiach. The Satmar Rav ztz’l says that Eliyahu Hanovi must come first as we don’t know how to build it so the geula will happen spontaneiously strictly from the heaven wthout our intervention. If we do, we violate the three oaths. This was an argument by the Meraglim who held that they must do it themselves as they are not for heavenly intervention.
