We need to specify what left anti-semitism consists of, in order to debate, educate, and clarify. These, I think, are its main features.
1. The belief that Israel has no right to exist. That is the core of left anti-semitism, though it comes in more than one version and from more than one root, ranging from the skewed anti-imperialism of the Orthodox Trotskyists through Arab nationalism to Islamic chauvinism. Advocacy of the destruction of Israel, which is what separates left-wing and Islamist antisemites from honest critics of Israeli policy, should not be tolerated in the labour movement and in the serious left.
2. The belief that Israeli Jewish nationalism, Zionism, is necessarily a form of racism. That this racism can only be expunged if Israel, Zionists, and Jews abandon Israeli nationalism and support of any kind for Israel. That Jewish students, for example, can only redeem themselves if they agree that the very existence of Israel or of an Israeli Jewish nation is racist.
3. The view that Israel alone is responsible for the conflict with the Arab states (and, now, with Islamic states). The idea that Israel alone is responsible for creating Arab refugees, and is uniquely evil in doing so. In real history the Arab states mostly refused the Palestinians citizenship or even the right to work.
4. The claim that the Palestinian have a “right of return”, that is, the right to the organised settlement in Israel of six million people (only a tiny and dying-off number of whom were born in what is now Israel) is one of the many codes for in fact demanding the self-abolition of the Jewish state and justifications for war to conquer and abolish it because it will not abolish itself. It is not the equivalent of free immigration to the UK, or even of mass migration to the UK of millions from Syria, Libya, and Africa. Its equivalent for Britain would be the settlement in the country, organised by a hostile authority, of sixty million people. Socialists should of course be in favour of agreements between Israel and the Palestinians for compensation and for letting individual Palestinians into Israel. Support for a collective right of return is only another form of the demand to conquer and destroy Israel, if it will not surrender.
5. The idea that the forced migration of 700,000 Arabs was a unique evil is also extravagantly wrong. In 1945, 12 to 14 million Germans were driven out of Eastern Europe. They were driven into a Germany reduced to ruins by wartime bombing, where economic life had seized up and millions were starving. Only fringe German nationalists now propose to reverse that forced population movement and to drive out the Poles, Czechs, Russians, etc. who live where Germans once lived.
6. There is a peculiar dialect of Holocaust semi-denial current on the left. I have never heard of anyone on the left who denies that six million Jews were murdered by the Nazis (though, in the nature of things, someone will now jump out from behind a bush wearing a “Hitler was Framed” badge, and call me a liar). What the anti-Zionist left habitually deny is that this unique fact of history had repercussions that we should at least recognise and try to understand, with some sympathy for the surviving Jews and their descendants. On the left the Holocaust is not denied, but it is relegated almost to the status of a “virtual fact”. In truth, the Holocaust discredited all Jewish-assimilationist programs, including ours, the socialist one. It created and hardened the will for a Jewish solution to the Jewish question and for the creation of Israel. There is nothing to be surprised at or scandalised by in that. The Holocaust should be appreciated as a real fact of history, with repercussions and reverberations, and not as something outside the history we are all part of, as a sort of side-show, as a two-dimensional hologram rather than the enormously weighty, reverberating event it was and continues to be.
7. The idea that there are good peoples entitled to all rights, and bad peoples, entitled to none. That too is something I have never heard anyone voice plainly and explicitly. But it is there as an implicit subtext in the idea that we are concerned with national rights only for the presently oppressed, i.e. in this case the Palestinians.
8. There is no one-state solution. Not, as now, by Israeli domination of the whole territory and Palestinians living indefinitely in a purgatory of Israeli occupation, nor through a Palestinian state “from the river to the sea” incorporating Israel after its Jewish population have been killed or overpowered by Arab or Islamic states. The only just solution that can serve both Jews and Arabs is two states: a sovereign Palestinian state in contiguous territory, side by side with Israel.
If, as may be possible, a Palestinian Arab state is made impossible by the spread of Israeli settlements, then the future will be grim indeed for both Palestinian Arabs and Israeli Jews.
