There certainly remains a wellspring of strong diaspora Jewish support for Israel, and even for many of its right-wing policies. But that support increasingly is limited to American Orthodox Jews, who themselves are increasingly alienated from the rest of the American Jewish community. (Most Americans who support right-wing Israeli policies are religious Christians, who far outnumber American Jews.) While the high birthrates of the Orthodox point to their growing proportion within the American Jewish community, there could not be an Orthodox majority among American Jews for several more decades. What this means is fairly obvious: If the American political class judges that U.S. interests in the Middle East and in Israel no longer warrant the attention and expense characteristic of the past half century, the power of pro-Israel sentiment in American society is increasingly insufficient to thwart or reverse that judgment.
