Jimmy Carter set out to be an exemplary ex-president -- indeed, to redefine that role into one involving a level of moral activism and diplomacy other former chief executives had considered unseemly. Rather than advancing American interests, however, he has become a hectoring critic of his country who exempts dictators from the high standards of human rights he otherwise claims as his legacy. The moral double standards are nowhere more visible than in his persistent and intemperate attacks on Israel, which are so obsessive as to raise the question of whether an agenda of anti-Semitism underlays the obvious anti-Zionism.
