He was in that rare space of occasionally making antisemitic statements while also being consistently pro-Israel, so on the presumption Israel is a Jewish nation, the grounds for an assassination attempt by an Israeli radical extremist is remotely plausible.

As a note, Israel is not a nation for Jewish people. It’s a nation for rich people who happen to be Jews. The class divide between wealthy Jews and working class Jews is historically greater than solidarity between them. (As it is with Christians, LGBT+ or most identities.)

There’s a lot of pro-Israel antisemitism cross-sectionality, especially in Protestant Evangelism as it is ministered in the United States.

The white Christian nationalist movement is pro-Israel specifically because they are looking forward to the second advent (the apocalypse in Revelation as a future prediction). One of the prophesied events as the end times approach is the return of the Jewish people to Israel. Hence, their pro-Israel efforts are part of an effort to hurry that process along. (Prophesies never ever worked that way, but whatever. It’s not my parade.)

But also in that same biblical interpretation, the Jewish peoples are damned to Hellfire while Christians (as narrowly defined by the movement) are gathered unto Heaven. So for the white Christian nationalist movement, Israel is a tool to serve its own metaphysical purposes.
