How do non-Dispensationalists interpret Genesis 12:3 which Zionist Dispensationalists use to support non-Christian Israel?

***Zionism*** (political nationalism) certainly was not begun by Dispensationalists; and the occurrence of the Halocaust did give impetus to it. But Dispensationalist have strongly embraced it. And Zionist Dispensationalists often quote the Genesis 12 verse, ***God will bless those who bless Israel, and curse those who curse Israel*** to justify their support, spiritually, financially, and militarily, for the nation of modern Israel. >I will bless those who bless you, and whoever curses you I will curse, and all peoples on earth will be blessed through you. (Genesis 12:3) This is even though the majority of the Jews in Israel are either ***secular, or anti-Christian***. And are seen to persecute Christians living there. (Statements by King of Jordon, and news reports on TBN network who reluctantly received his report until they saw videos themselves of Jews disrupting Christian rites). And ***Christian Palestinians*** are not even on their radar screen! So how do ***protestant orthodox Christian scholars*** deal with this seminal verse about blessing Israel in contrast to the Dispensational interpretation? Which other scriptures do non-Disp. Christians appeal to, that causes them to treat ***all nation equally***, with love and mercy, without referring to any particular nation or political entity?
