I can see why decent people might support JVP/BDS out of profound frustration with Israeli policy toward the West Bank — yes, the West Bank, the Occupied Territory, not the Biblical lands of Judea and Samaria. I understand their outrage but think they're being fooled since, if you take care to look into it just a bit, it becomes obvious that Omar Barghouti and other founders/leaders of JVP are not interested merely in addressing Israel's proto-apartheid policy toward the West Bank; no they think of Israel itself as just another, bigger, illegal settlement.
Then I read statements like those made by Mahmoud Abbas, President of the Palestinian Authority in Ramallah this past weekend. In them:
[he] gave a lengthy history lecture reaching back to the 17th century, saying that Oliver Cromwell had first proposed shipping European Jews to the Holy Land, before tracing the beginning of Zionism to what he called the 19th-century journalist and activist Theodor Herzl's efforts to "wipe out Palestinians from Palestine."
"This is a colonial enterprise that has nothing to do with Jewishness," Mr. Abbas said. "The Jews were used as a tool under the concept of the promised land -- call it whatever you want. Everything has been made up."
If educated, senior (if not yet certifiably senile) leaders of the Palestinian movement think "Jewishness" has nothing to do with the creation of Israel, and that the notion of "the promised land" is alien to Zionism and the creation of Israel, well, that's uniformed, fantastical and more than a little crazy.
It's exactly the sort of nonsense that will buttress the other side, the likes of JVP/BDS.
