In rare remarks on Egypt’s governmental crisis, Prime Minister Benjamin Netanyahu has suggested that the fall of President Mohammed Morsi demonstrates the weaknesses of political Islamist movements.

“I believe that over the long haul these radical Islamic regimes are going to fail because they don’t offer the adequate enfranchisement that you need to develop a country economically, politically and culturally,” Netanyahu told the German weekly Welt am Sonntag.

He said he thought radical Islamism was wholly unsuited to dealing with a global economic and information revolution, and “goes right back to medievalism against the whole thrust of modernity, so over time it’s bound to fail”.

Jerusalem had previously responded more cautiously to Morsi’s removal by the Egyptian army on July 3. Netanyahu avoided any comment at the time, though a confidant expressed hope that Egypt’s new leaders may restore Cairo’s largely frozen contacts with Israel.

In the interview, Netanyahu reiterated Israel’s concern that the U.S.-brokered 1979 peace treaty with Egypt remain intact, alluding also to a surge of violence in a Sinai border region since Israeli ally Hosni Mubarak was toppled from power in Egypt two years ago.

“Preserving the peace with Egypt through these convulsions is of central importance to us,” Netanyahu said.
