Rabbi Yitzchak Yaacov Reines, Rabbi Abraham Isaac Kook, Rabbi Joseph Ber Soloveitchik, Rabbi Yitzhak HaLevi Herzog, Rabbi Ben-Zion Meir Hai Uziel, and Rabbi Aharon Lichtenstein were among the greatest Torah sages of the past century and they were all enthusiastic Zionists.
“not there entire State of Israel is in Eretz Yisroel. Eilat, Israel
is in chutz l’aaretz. And not the entire Eretz Yisroel is in the State of Israel”
