It's not obscure. OP is actually making it sound weirder by highlighting specific requirements of one "flavor" of the prophecy. It's actually a common belief of evangelicals and Mormons alike. Everyone I know understands at least some of this, like the requirement of the temple being rebuilt. I'm not knowledgeable on scripture but it's supposedly biblically based in Revelation. Christians and Jews have different perspectives on the prophetical points. Jews think the messiah will come while Christians know it as the antichrist. Christians don't actually care about the red heifer but they're perfectly willing to let Jews go through the motions and see what happens. Most Christians would say you can't trick God and it's wrong to try and force prophecy, but if certain coincidences start lining up they aren't going to say it's NOT prophecy coming true.

Still, it would be wrong to blame American Christians as the ones driving unconditional support of Israel. Politicians would do that anyway because they're bought and paid. What the belief allowed was the coopting of American conservatives by the deep state of Israel, since religious people look the other way when they hear news about Israel spies, or undue amounts of money being sent there - rather than complain to their congressman like they might otherwise.

It might be more accurate to say that Christian end-times thinking is part of what allowed the creation of Israel in the first place via Great Britain partitioning the region.
