Carter was quoted in an interview with the Arkansas Democrat-Gazette as calling the Bush administration the "worst in history."
When he was subjected to a barrage of criticism [former Presidents usually don't openly attack current administrations) instead of standing his ground he blamed others and said his "words were taken out of context."
He then twisted himself into a pretzel saying he was comparing this administration's foreign policy with that of Richard Nixon's. According to Carter, Nixon had a productive foreign policy.
In fact his words were not taken out of context. What he actually said was:
"I think as far as the adverse impact on the nation around the world, this administration has been the worst in history." "The overt reversal of America's basic values as expressed by previous administrations, including those of George H.W. Bush and Ronald Reagan and Richard Nixon and others, has been the most disturbing to me."
Irrespective of what people might think of the Bush administration, what this demonstrates is how Jimmy Carter is always quick with some excuse or ready to blame others for his problems.
