Jeff Goldberg writes:
The settlement movement, its supporters, and its apologists (in Israel and in America) have successfully conflated support for their movement with support for Israel and for Zionism itself. They have created a reality in which criticism of the settlement movement has come to equal criticism of Israel. You see this at the AIPAC convention, where no speaker dared suggest that the settlements are, in fact, the vanguard of Israel’s dissolution, rather than the vanguard of Zionism. (I explain why the settlements could lead to the end of Israel here.)
If you read his whole post, you’ll notice that Goldberg writes that “the settlements should be fought as if there was no such thing as anti-Zionism, and anti-Zionism should be fought as if there were no such thing as the settlements.” For the sake of context, this is a riff on prominent Zionist (and eventual first prime minister of Israel) David Ben Gurion’s famous dictum during World War II regarding the White Paper of 1939 which called for the creation of a shared Jewish and Arab state in the British mandate of Palestine. Ben Gurion said that “we must assist the British in the war as if there were no White Paper and we must resist the White Paper as if there were no war.”
