“The Pro Zionists have made yishuv Eretz Yisrael into the first and foremost mitzvah in the Torah.”
Well the first Rashi in the Torah does say that the first 61 chapters in the Torah are primarily to remind ourselves that the Land of Israel is ours.
And without the State of Israel there would be essentially no Jews in the Land of Israel today. At its worst the State is Israel is as good as any non-Jewish government.
