Whether the Democratic Party can liberate itself from AIPAC's influence is highly doubtful. Any politician who dares to expose AIPAC's influence would incur its wrath; so very few can be expected to do so. It is up to the American Jewish community itself to rein in the organization that claims to represent it. But this is not possible without first disposing of the most insidious argument put forward by the defenders of the current policies: that the critics of Israel's policies of occupation, control, and repression on the West Bank and in East Jerusalem and Gaza engender anti-Semitism.
The opposite is the case. One of the myths propagated by the enemies of Israel is that there is an all-powerful Zionist conspiracy. That is a false accusation. Nevertheless, that AIPAC has been so successful in suppressing criticism has lent some credence to such false beliefs. Demolishing the wall of silence that has protected AIPAC would help lay them to rest. A debate within the Jewish community, instead of fomenting anti-Semitism, would only help diminish it.
The AIPAC warmongers hide behind 'anti-Semitism' the same way Bush hides behind 'support the troops'. Both positions are crocks of shit and need to be shown up for what they are: False issues to cover crimes.
