because they care that Israel exists to fulfill their end times theologies.
I feel that this should be expanded on.
According to Christian evangelicals, to bring about the End Times and the Second Coming, all of the “Children Of Israel” (Jews) need to be “Gathered In The Land Of Israel”. Once “Assembled”, the gathered Jews will have the Christian Gospels preached at us, whereupon 144,000* Jews will spontaneously convert on the spot. All of the Jews then die, and those who converted ascend to Heaven, while the rest go down to Hell. Those who ascend to Heaven then bodily return as the escort of Jesus Christ.
I first heard of this from a missionary who was trying to convert me and I was fending him off using quotation from his own text. And in the end, his eyes shining with the fervor of a True Believer, he told me that he was jealous of me, because I was sure to be one of the Elect with my knowledge of the Christian Bible.
I asked him what he meant by that, and was told about the above “prophecy”–and, he was quick to assure me, that with my knowledge of Christian scripture, I was certain to be one of those 144,000 who saw the light and converted when the time came. And thus, to his mind, I was in a position where I would meet Jesus first.
He just told me that in his religious worldview, I exist to be nothing more than a blood sacrifice to bring his god back, and he was jealous. It was one of the most terrifying moments of my life, seeing someone looking at me not as a person, but as a thing.
Since then, I’ve had it sadly confirmed that this is an incredibly widespread belief among Christian evangelicals, which is important to remember–they support Israel because they need their human sacrifices for their god.
* As an aside, I love the precision of that number. Exactly 12 Apostles times 12 tribes times 1000.
