The article in question is on page 12, and is entitled Obama and the Muslim Agenda. The relevant quote appears at the bottom of the first column, and continues tp the top of the second:
My wife Rachel, who monitors Arab language broadcasts for Israel Radio, picked up a revealing statement on the Round Table Show on Egypts Nile TV. Egyptian Foreign Minister Ahmed Abul Gheit said he had a one-on-one meeting with Obama, who told him that he was a Muslim, the son of a Muslim father and stepson of Muslim stepfather, that his half-brothers in Kenya were Muslims, and that he was sympathetic to the Muslim agenda. He asked the Arabs to show patience. Obama promised that once he overcame some domestic American issues (like healthcare reform), he would show the Muslim world how he would deal with Israel.Pro-Arab, so-called Christian presidents are one thing. But how concerned should we be if the US President is a Muslim who is loyal to the Muslim agenda to isolate and weaken Israel? When the Palestinians talk about nothing but war with Israel and its annihilation, and the president of what was our strongest ally backs their demands for a state with Jerusalem as its capital, and adheres to the same faith, should we not be warning the American public?
