Signed, Iraq war vet (it was more for Israels interests than ours!)
That would be odd way of serving the Israeli interest, as the actual Israeli government opposed the Iraq war and thought it would be bad for Israel:
Here’s the source I usually use[1]: 45% of American Jews consider Israel essential to them. Another disjoint minority consider it “important but not essential.” Neither of these imply support for the Israeli state, and neither separates the importance of Israel qua state or political institution from Israel qua the family our loved ones of the people being polled.

It's my understanding that pro-Israeli sentiment on the right is somewhat rooted in antisemitism in the first place. They love the idea of Jews having their own country away from everyone else.
Besides, the whole Q conspiracy wing currently taking over the American right is blatantly antisemitic.
There are a few things going on: Jewish Americans vote overwhelmingly for Democrats, there is a powerful (and loud) conservative pro-Israel lobby, and hardline conservative Christians overwhelmingly support Israel - likely Israel's most powerful American constituency.
