The reason for the support matters.
A lot of them think support for Israel leads to the apocalypse and Jesus’s return. It doesn’t end well for the Jews in that story.
Now you're confusing maga with evangelicals which are very different parts of the party. Evangelicals have largely lost influence in a post Roe world.
Trump had to cater to them in his first term but, since he's taken over the party, they're in the backseat.
Among USA evangelicals, support for Israel (and specifically the country’s belligerence) has notably little to do with Judaism itself or the Jewish people.
