I have contended in the past that right wing Jews who claim to be motivated by love of Israel to support Republicans are actually trying to do the inverse. They are motivated by love of Republicans and are to use Israel as a wedge to benefit Republicans. It is like the tail wagging the dog. I think this has been completely laid bare in the most recent election.
For people of all political stripes who care about Israel, this presents a huge potential problem. Like any wedge issue, this one may have its intended effect and divide the electorate. Given that we have had and currently have an electorate that has been largely supportive of Israel and Americas ties to Israel, this is a very bad thing for people who support Israel.
Support for Israel in American political discourse has long been bi-partisan, and it still largely is. It is one of the rare issues that is so in our hyper-polarized age, and that has been an amazing gift for American supporters of Israel, allowing us to maintain America's crucial support for Israel through different administrations and Congressional changes. However, if right wing Jews succeed in making it a wedge, then support for Israel will no longer be bi-partisan. Support for Israel will be identified with one political party, and then by definition be shut out of power half the time.
I read such intense vitriol directed at liberal Jews from right wing Jews. They think that liberal Jews are all communist agitators who want to bomb Israel off the face of the Earth. This post from PJ media is a typical example. It makes me wonder if those kinds of authors and the commenters have ever actually met any liberal American Jews or have ever been to the places where they live. Or if they have ever been to Israel and seen the tremendous political diversity among Zionist Jews there.
It is clear that right wing Jews are trying to drive the message that if you support Israel, you have to be on the right wing. They've even demonized Alan Dershowitz, who is one of the most important pro-Israel voices in America, because he is a Democrat. And the amount of vitriol that they've directed at President Obama is astounding, brazenly calling him an antisemite. Whether one loves or hates his policies, it is clear that the President is not an antisemite, given that people closest to him in his inner circle have included, for example, Chiefs of Staff Rahm Emmanuel (served in the Israeli Army) and Jack Lew (Orthodox Jew).
Liberal American Jews won't, en masse, turn on Israel if a wedge is driven by these right wing Jews, but liberal non-Jews will. There is creeping anti-Israelism and anti-Semitism on the left, as evidenced by the antics at places such as Daily Kos and Huffington Post that have been documented here and elsewhere. If support for Israel becomes identified in the public discourse as a "right wing" or "Republican" thing, then it will push much of the left to be against that, and into the opposite camp. That's how polarized American politics works, because most Americans, left and right, buy their politics wholesale and don't follow individual issues carefully.
By trying to force a wedge to boost Republicans, right wing Jews are endangering Israel.
It would be slightly less ridiculous if right wing Jews were at least succeeding in boosting Republicans with these shenanigans, but even that doesn't seem to be the case. In spite of the last several years of constant shrill vitriol against the President, Democrats, and liberal and centrist Jews, and the hundreds of millions of dollars thrown in by the likes of Sheldon Adelson, the President was reelected this week, Democrats had a substantial nationwide victory, and studies indicate that the Jewish vote hardly moved from being solidly Democratic.
Support for Israel has been amazingly bi-partisan and enduring in American politics in recent decades, and that has been one of the greatest benefits to Israel as it faces constant challenges from its hostile neighbors. But now, right wing Jews, by dishonestly presenting support for Israel as exclusively a right wing trait and demonizing famous liberal supporters of Israel, are trying to force American discourse on Israel away from a somewhat broad bi-partisan consensus and toward partisan polarization. They may very well succeed, and this will profoundly harm Israel.
If right wing Jews really care about Israel, they should cease trying to use it as a wedge, and accept that support for Israel should be bi-partisan to the largest extent possible. If instead, what they really care about is advancing Repubicans and Israel is simply a means to that end, then it is obvious that they will continue to do as they are doing, and Israel will suffer for it.
