In an interview with PBS Frontline:

“Hamas is going to destroy Israel? [laughs] Because we have a nuclear weapon and F-16 jets and Apache helicopters and because, all the time, we are killing Israelis this is policy that is not acceptable. We are [using] primitive weapons to defend ourselves, to push the Israelis outside our land. So I think the question should be answered by the Israelis: Who is going to destroy the other? The people who occupied our area in 1948, who reoccupied our area in 1956, the people who reoccupied our land and Arab land in Syria, Lebanon, Jordan and Egypt in 1967, who went to Lebanon and killed thousands of people in the refugee camps of Sabra and Shatila. Who is going to destroy whom?” Frontline, “Extended Interviews Mahmoud Zahar,” PBS, May 9, 2006, https://www.pbs.org/frontlineworld/stories/palestine503/interviews_zahar.html.
