Firstly the texts used in Halacha were often written in the Land of Israel. Shulchan Aruch was written in Tzfat and the Mishna was compiled in Zippori. the Haredi Rabbis were here long before the Zionists and actually began to build new settlements long before anyone called anyone a Zionist. many of those you condemn as outsiders, or foreigners have lived in Jerusalem for 10 Generations, going back over 200 years.
