This says it squarely:
What would compel a former U.S. president to pen a piece supporting an Islamic terrorist organization? Or perhaps Carter agrees with Nancy Pelosi that Hamas is a humanitarian organization. Jimmy Carter’s position reflects the deeply rooted anti-Semitism that exists in the Democrat party. It is a fundamental position of the progressive socialist Left…
…the delusion of Jimmy Carter in believing Hamas, a terrorist organization, deserves legitimacy. He believes an Islamic terrorist organization whose charter calls for the destruction of a sovereign state will lay down its weapons once provided with the “right incentives” — what exactly are those? In other words, Carter, like Neville Chamberlain and Obama, believe that appeasement and negotiation with evil results in peace.
via Jimmy Carter leads the Democrat charge for anti-Semitism.
