Thank you Citizen C for pointing this out. I am glad more people are talking about this problem: the Jewish far left's belief that the Israel Lobby is not very powerful and should not be viewed as a cause of US support for Israel. That is the view of Jewish Voice for Peace (JVP) and the US Campaign for Palestinian Rights.
As absurd as that belief is, many in the Jewish far left cling to it like a religious dogma, even though all the evidence points to the contrary-- points to the fact that the Israel Lobby is very powerful. The Lobby routinely intimidates journalists, congress, and presidents. It skews US policy toward supporting Israel, and has been doing that for a long time.
But the Jewish far left refuses to see it, because they believe that US capitalist imperialism is the source of all problems. It is heresy for them to think that a special-interest group is skewing US policy to make it worse. They believe US policy is inherently bad because of US imperialism. Blaming any other entity makes no sense to them. They have a "blame America first" and "blame America only" mentality.
This is counterproductive from an advocacy perspective, because it leads the Jewish far left to say things like: 'The Israel Lobby only lobbies the US to do what is in the US national interest-- and what the US would be doing anyway.' and 'The US supports Israel because it is in the US national interest to do so.'
Those perspectives hinder our efforts to persuade Americans that support for Israel is harming America.
The other harmful thing Jewish-far-left groups like Jewish Voice for Peace do is attack fellow activists who talk about the Israel Lobby as a powerful influence. I am convinced that is why JVP attacked Alison Weir so harshly and tried so hard to destroy her credibility.
I think that top JVP leadership believes that anyone who says the Israel Lobby is the main cause of US support for Israel is simply repeating an antisemitic "trope." That makes the person an antisemite in the eyes of JVP. Alison Weir says exactly that, so JVP is convinced she is an antisemite, based on that alone. That was enough 'proof' for JVP to spend a lot of time and money trying to destroy the reputation of a long-time, effective Palestine solidarity activist who was doing a lot of good work.
That is what I call putting your own far-left agenda ahead of the Palestinian cause. That is what I call de-facto collaboration with the Israel Lobby to take town a Palestine solidarity activist. That is why I could no longer remain a member or leader of JVP.
