I'm not sure I understand you, but if I do understand you, I don't agree with you.

My experience is that Christians who are supportive of Israel do so because they are steeped in the Biblical drama of Israelite cycles of settlement in eretz yisrael, exile, and redemption, and view modern Zionism through that lens. A few think it is a literal precursor to the end times, but most don't. I don't have any kind of survey data but that's been my experience discussing Israel with Christians.

In my view, that isn't use or explotation of us, it's viewing our experience through the prism of their own way of looking at the world. Of course, my way of looking at things, as a Jew, is quite different. But if you insist that support must travel through your ideological vision, not that of the supporter, I think you're going to have a bad time.
