Zbigniew Brzezinski, a foreign policy adviser to Sen. Barack Obama’s (D-IL) campaign, wrote in a Washington Post op-ed Sunday that a “sensibly conducted disengagement will actually make Iraq more stable over the long term.” He also called for engagement with Iran and said the United States should push Israelis and Palestinians to “start making the mutual concessions without which a historic compromise cannot be achieved.”

Sen. Lindsey Graham (R-SC), a supporter of Sen. John McCain’s (R-AZ) bid for the presidency, defended McCain’s backing (FOX) for a continued robust U.S. military presence in Iraq. Sen. Jack Reed (D-RI), however, warned that an “indefinite, open-ended commitment will not prompt the Iraqi political leaders to take important steps politically which they must take.”
