The aggressively photogenic John Edwards was cruising along, detailing his litany of liberal causes last week until, during question time, he invoked the "I" word -- Israel.

Perhaps the greatest short-term threat to world peace, Edwards remarked, was the possibility that Israel would bomb Iran's nuclear facilities.

Support for Israel in the U.S. has lately become bafflingly multi-cultural, representing an alliance between diaspora Jews, traditional Zionists and evangelicals. Support from Christian zealots, who now represent about one third of Israel's tourist business, is welcomed even though, according to evangelical doctrine, Judgment Day will bring the ultimate destruction of Israel and death to most of its residents.

The Economist observed this week that "knee jerk defensiveness" of Israel ultimately will erode support for that country around the world, even among Jews. Only 17% of American Jews today regard themselves as "pro-Zionist," the magazine points out, and only 57% say that "caring about Israel is a very important part of being Jewish." And Jimmy Carter only exacerbates these mixed signals with his recent perorations that Israel must "give back" territories to the Palestinians.
