Currently, there is much debate, and scathing criticism from Netanyah’s Likud party, in Israel over the “Blue & White” party’s possible alliance with Israeli Arab parties in a coalition following elections next month.
From the Torah perspective, there is no longer any way to identify descendants of Amaleiq. There has never been any barrier to any other Arab embracing Torah and becoming an Arab-Jew!!! An Arab can become a Jew just like any other race!!! Torah is not racist! (Only some Jews are racist.)
While there is no inherent incompatibility between Arabs and the Israel Nationalism Law, nor any justifiable religious reason, anti-Arab racism is, nevertheless, rampant and increasing among Jews, especially among Orthodox Jews and most especially among Israeli “Rightist” Jews.
Conflict enters the Israeli Jewish Right controversy from two fronts:  Islam and  racism.
Not all Arabs are Muslims. Where non-Muslim Arabs are concerned, there is no nationalistic threat from non-Muslim Arabs.
Ergo, where the argument isn’t over Islamist threat relative to Torah and a Judaic state for Jews, a priori, all other anti-Arab sentiments are racist!
This transfers focus directly to contra-Torah, racist reforms by Dark Ages-oriented European Orthodox (spurred by the Ultra-Orthodox Kha•reid•imꞋ) Jews; definitions and views internalized from standards imposed by Hitler and the Nazis.
Far bigger, and greater existential, threats, in my view, are  Orthodox racism and  Orthodox Chief Rabbi and Rabbinate efforts to cut themselves and Israeli Jews off from the non-Orthodox 85% of world Jewry! Arrogantly convinced that they are peers decreeing for ha-Sheim, they don’t realize that they are sawing the limb they are sitting on.
