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.

Regardless all of the major Jewish denominations in the US (reform movement, conservative movement, modern orthodox and even most of the heredi movements these days) officially support Zionism. Now you have individuals in each group who may describe themselves as anti-Zionist, but it is a very small minority (although growing in the reform movement).
Among non affiliated Jews the percentage of anti Israel/anti Zionist Jews may be a bit higher but it is still pretty low. It’s no where near millions (you only have 6.5 Million Jews in the US).
Now none of the above means that there is not a large segment of pro Israel, American Zionist Jews who are against a lot of the current and previous governments policies when it comes to the West Bank and Gaza (or in general).
Heck I am a Canadian born Israeli, who is personally against a lot of the policies of the Israeli government. I quite often cringe at some of the comments and actions of some of our politicians. On the bright side it helps me chose who not to vote for
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.
