But the high-water mark, ironically, comes just as younger American evangelicals are growing less attached to Israel. Recent polls have sparked anxiety among Israeli officials and Christian Zionist groups, which are trying to reverse the decline.

Faced with the dip in support, Israel is increasingly looking to evangelical communities in Latin America, Africa and elsewhere to build international support. Guatemala, where President Jimmy Morales is an avowed evangelical, was the first country to follow suit after the U.S. recognition of Jerusalem.

“I find it funny because it took me 20 or 25 years to get the Jewish community to see the benefits of working with the evangelical community, and now [Jews] are so concerned with the diminishing commitment they have to Israel,” said Rabbi Yechiel Eckstein, an American Israeli who played a key role in fostering the relationship between American evangelicals and Israel.
