Barack Obama says Israel is " America's strongest ally in the Middle East," but skeptics contend he's soft on the Palestinians and not tough enough on Iran. Hillary Clinton promises "massive retaliation" if Israel's ever attacked by Iran, and an "umbrella of deterrence" that would go beyond that. These and other differences have been used to suggest that Obama's support of Israel is insufficient. Does Obama suffer from guilt by association with his church pastor and others? Who are the real advisors to his campaign? Does Clinton really support a two-state solution? What about a pre-emptive attack on Iran?
