The deceptively named "Jewish Voice for Peace" is an organization of extremists who are not for peace but are against Israel. Funded by a foundation that also supports the aptly named Electronic Intifada, JVP are what you might call a "self-hate group." They exploit the "J" in JVP to express what in fact are malevolent impulses aimed at the Jewish state, while reveling in the unearned moral credit they like to imagine accrues to those who distance themselves from the racist caricatures of Zionism in circulation these days.
The real Jewish voice that's actually for peace are those in Israel who have offered it repeatedly--only to have sound proposals rejected again and again. Including as recently as 2000, 2001, and 2008. Not to mention the brave Israeli soldiers who defend the Middle East's only vibrant liberal democracy, an island of peace and stability in a violent region.
No, supporting JVP is not supporting peace. Clicking "like" on their page might make know-nothing far-leftists feel good, but that's silly. Indulging your philosemitic antisemitism (or is it antisemitic philosemitism?) helps no one but your narcissistic self. JVP may have given you "permission" to oppose Israel's very existence by inviting you to join them in supporting BDS, etc., with a guilt-free conscience. Such is their mandate. Such is their hypocritical role in the current propaganda war against the Jews. They are there to koshers and give a hechture to bigotry. But that doesn't make it right and no amount of "Jew washing" today's genocidal anti-Zionism excuses those who objectively support terror and death, while loudly proclaiming they are for nothing but peace and love.*
Where is the Palestinian Voice for Peace (PVP)? What does the voice of Hamas say about peace with "the sons of apes and pigs" (as the Hamas Charter refers to Jews)? Where is the willingness to negotiate on the part of the Palestinian Authority (PA), so focused instead on taking Israel to court internationally? What does Iran say about living at peace with the little Satan, explicit target of its hideously bullying nuclear program? What do the voices of the mullahs say about wiping out the Jews? And how does the voice of Iran's proxy in Lebanon, Hezbollah, sound?
By contrast with the enemies surrounding it--who have never accepted a sovereign Jewish presence in the Middle East--the modern Hebrew republic--both its citizens and successive governments--has long been the loudest, clearest voice for peace around. And this is the Jewish voice that liberals, progressives, and conservatives alike should be listening to and supporting--in the name of a lasting peace that can only come with the defeat of terrorism and antisemitic anti-Zionism.
*As an antidote, see a couple of great books on the subject of Jewish antisemitism (which JVP personifies), one old and one new. The classic text on the subject, by the great Sander L. Gilman, is Jewish Self-Hatred: Anti-Semitism and the Hidden Language of the Jews (Johns Hopkins, 1986), and the best thing on it lately is the amazing Eddie Alexander's must-read, Jews Against Themselves (Transaction, 2015).
