The Muslim Brotherhood has undermined the stability of the Arab world at the time Israel is safe and in peace with the group, former Yemen president Ali Abdullah Saleh said. If the Muslim Brotherhood had rallied against Israel in the past 50 years, Israel would now have become history and Palestinian lands would have returned to their owners, the former president wrote on his Facebook. He lashed out at the group, saying it has been mobilizing against Arab nations while doing nothing against Israel in the past 50 years. He condemned the group’s allegations that it was defending legitimacy, saying the Muslim Brotherhood was not a supporter of any revolution and does not believe in legitimacy.
