Don’t have time to address all your points at the moment but will get back to you. In the meantime a rebuttal on Christian fundamentalism.
I’m not saying all American Christians are fundies but the number isn’t trivial. Hagee led CUFI which you mention alone has 10 million members. And it has a regular stream of major GOP leaders, with indirect access to WMDs, that cheer them on. Netanyahu. has been associating with CUFI for decades because they are more uber Zionist than most Jews but for their own unhinged ends.
There is also the matter of polling (2024 Gallup) suggests around 37 percent of Americans still claim humans were created in present form in last 10,000 years. This is code words they are creationists trying to match their religious myths to reality.
Even some Kach sorts have picked on they are playing with fire when it comes to their alliance with Christian fundamentalist elements in America. The US used to be pals with the Afghan mujahideen back in the 80s when the used them as a proxy against the Soviets. Didn’t work out so hot. Proverbial chicken will come home to roost if not called out.
