The end of zionism?

This David Hearst article appeared in the main section of The Guardian yesterday.  In it he explores the possibility of a one state solution for Palestine:

 If Israel ends its occupation of the West Bank, and allows it to join with Gaza, the result could be two states – a Palestinian one alongside an Israeli one. But if you accompany that with a civil rights movement inside Israel, the goal could be very different – a secular, democratic state "for all its citizens", where Jew, Christian and Muslim are equal. A one-state solution in which Jewish citizens lose an inbuilt majority. The end of Zionism, no less.

It's a fairly innocuous article but it seems to have caused some panic at Harry's Place.

UPDATE: From Wodge in the comments:  The panic seems to have spread with Norman Geras reporting the article under the headline, To hell with the Jews, no less.  In his panic he went and let on as to why Jews are not a suitable case for self-determination which he takes to mean granting people of a given ethnicity a power of veto as to whether compatriots can come, remain or return to their homeland.  A quick surf around other usual suspects suggests that it must be August and some dodgy academics are on holiday.
