Prime Minister Benyamin Netanyahu’s far-right, Jewish nationalist, ultra-conservative coalition government threatens to put the Jewish state on a collision course with Diaspora Jewry and could weaken or undermine a pillar of Israeli national security: unquestioned US support. The looming crisis with two of Israel’s crucial constituencies, the United States and Diaspora Jewry, stems from Mr. Netanyahu's embrace of the far-right and willingness to sidestep the rise of anti-Semitism among Christian nationalists and Evangelicals, two groups that constitute the mainstay of US grassroots support for Israel.
