Most American Christians support Israel because: 1.) they have generally positive opinions of Jews as people. And (2.) after the Holocost, it seems reasonable that the Jews should be allowed to form their own nation so that they would not be subject to the notions of the the "King" or majority.

Rather, I perceive that most Christians have, at best, an ambivalent opinion of Jews and Judaism: They have no concept of Judaism as other than a precursor to Christianity; and Jews are an enigma in their rejection of Christ as the Messiach (or an avatar of God).

Further, though many American Christians support Israel as the homeland for the Jews, and as a Jewish state, I think they most often see it in the same context as Pastors Hagee, Parsley, et al., who perceive of the State of Israel as primarily a necessariy element in Christian salvation and dominance.
