Mike's post this Sunday at Elder of Ziyon raised the important question of what use would an alliance with the Left be for us. In the comments, I pointed out that the Left encompasses those who are irreconcilable, those who are committed to our side, and those to whom we must reach out. Mike replied by asking how I propose to reaching out to that segment of the Left.
To summarize my point from my comment at EoZ, opposition to Israel from the Left generally stems from a combination of a conviction that whatever positions the Left takes, anti-imperialism trumps all, and that Israel is an outpost of Western imperialism. The Left consists of factions that are committed to those two points, factions that are ardently opposed to those two points, and factions that have not made their assessments on either point. In actuality, there is a fourth group on the Left, that which doesn't really care about any of the Left's agenda other than demonizing Israel and Jews, but wants to couch its judeophobia in the language of basic human decency that the Left ascribes to anti-imperialism.
With that, the challenge is to move as many members of the non-committed factions of the Left to one of the factions opposing the notion of anti-imperialism trumps all and/or the notion that Israel is a colonialist outpost. I don't have sufficient information to answer the question of how to reach out to them for that effect. However, I would like to suggest what information would be needed in order to formulate an outreach strategy. The main criterion is interfering with how the BDS activists seek to convince the non-committed elements of the Left to support their side.
Getting more specific about how to reach out to the non-committed factions, there are two possible ways to sway them. One is to convince them that while opposing imperialism is a positive value, it should not trump all other liberal value. This avenue might be tricky because the relative importance of opposing imperialism compared to other liberal values is strictly a matter of opinion. The one suggestion I can offer would be to highlight the motives of those who are pushing the notion that anti-imperialism should trump all. Specifically, we could point to the sector of the Left that does not care about any of the Left's objectives, but latches onto the Left in order to exploit the language of anti-colonialism for the purpose of promoting their judeophobic ends.
The other potential way to sway the non-committed Left would be to challenge the notion that Israel is a colonialist outpost. There is an objective case to be made that Israel is not an imperial entity, but not within the eurocentric narrative. The reality is that for any wrong committed by Europe against us throughout history, including the Holocaust, the BDS activists will claim that answering them by "dispossessing" the "Palestinian people" by the establishment of Israel constitutes answering a wrong with another wrong. What's needed is a focus on Middle-Eastern Jews and their history. The purpose of doing so would be to cast the Middle-Eastern Jews as the historically dispossessed people and Zionism as the movement which as a side-effect brought them dignity.
