Barack Obama claims to support Israel, but very simply, I don't trust him. Look at his foreign policy team, which originally included Samantha Power and Robert Malley, two prominent anti-Israel academics. They were forced to resign when their presence on the Obama team became a source of embarrassment to the Democratic Presidential candidate. Now, we have Zbigniew Brzezinski, a steady critic of Israel (and the former Secretary of State under President Peanut Farmer) who has recently spoken out in defense of the Walt & Mearsheimer screed claiming that those nefarious Jews were manipulating American foreign policy for their own ends: http://www.nysun.com/national/dershowitz-obama-should-repudiate-brzezinski/62439/. Funny how Brzezinski , who asserted that the Israeli military was engaging in actions that amounted to "killing hostages" in the Second Lebanon War in 2006, seems to have absolutely problem with the Saudis or other Arab states lobbying the U.S. government.
In any event, Senator Obama seems to have this unfortunate tendency of associating himself with people who don't like Israel too much (does the name Jeremiah Wright ring a bell to anyone?), so I really have to wonder how any supporter of Israel can at the same time support him?
