I was told that Rothschild wanted to purchase the temple mount when he was purchasing land in Israel, but did not because the Rabbis were against it
What were the reasons the Rabbis were against it?
Are there responsa regarding this (which I can read)?
Rabbi Zvi Hirsh Kalisher, a leading figure in this effort, turned in writing to the greatest Jewish philanthropist of the age - Baron Asher Anshil Rothschild, who commanded the respect of all the world's royalty. R. Kalisher suggested that he offer to purchase the entire land of Israel at a high price from Ibrahim Pasha, King of Egypt, who ruled over the Holy Land at the time. The land itself was barren and desolate. R. Kalisher also suggested an alternative possibility, in the event that the first one should be rejected - to request the minimal purchase of Jerusalem and the Temple Mount. The Rabbi explains at great length, how the renewal of the Temple service will lead to the mass immigration of the Jewish people from the lands of their oppression, resulting eventually in the settlement of the entire land of Israel
