I’m not sure how one can separate the occupation from Zionism. The occupation happened because the Zionists who are colonial settlers have taken over the land, believing that they have the intrinsic right to do so because god ordained that they have it.
The other thing that I may have a quarrel with, not sure, is that the author describes 1967 as the date when the occupation occurred. The NAKBA happened in 1948 and I therefore believe that the beginning of the occupation began then. The whole enterprise was a colonial settler state organized by the British but with the support, encouragement and backing of the Zionists who supported setting up a Zionist capitalist state.
