US President Barack Obama and Israeli Prime Minister Binyamin Netanyahu held a joint news conference ahead of their White House meeting Monday. Referring to the two issues on which they differ, Obama said there was still time for a two-nation solution of the Israeli-Palestinian conflict, adding he was committed to preventing Iran obtaining nuclear weapons. Netanyahu: The Palestinians are not pulling their weight for a political solution of the dispute. The people in Israel, he said, "expect me to stand up to pressures." The two leaders then started their face to face talks behind closed doors.
