President George W. Bush

Carter was critical of the George W. Bush administration, publicly lambasting the president and his handling of the Iraq War in a 2007 interview.

“I think as far as the adverse impact on the nation around the world, this administration has been the worst in history,” Carter told The Arkansas Democrat-Gazette in a phone interview.

He continued, “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.”

A White House spokesperson responded at the time, according to The New York Times, calling Carter “irrelevant” and “sad.”

But Carter later offered Bush praise; at the 2013 opening of the George W. Bush Presidential Center, Carter extended his “admiration” to the 43rd president, heralding Bush for keeping his word and acting to end a 20-year civil war in Sudan.

“In January of 2005, there was a peace treaty between North and South Sudan that ended a war that had been going on for 20 years,” Carter said. “George W. Bush is responsible for that.”

President Bill Clinton

As president, Bill Clinton took Jimmy Carter up on an offer to help de-escalate tensions with North Korean leader Kim Il Sung, according to the Clinton Library.

“The use of President Carter to resolve this conflict proved complicated, when he announced an unofficial agreement with North Korea to bring an end to the stalemate on CNN before allowing the Clinton Administration officials to review the agreement,” the Clinton Library said in a brief history of their relationship.

Carter later joined a diplomatic team along with former Chairman of the Joint Chiefs of Staff Colin Powell and Sen. Sam Nunn of Georgia to help “avoid an armed conflict with the military leaders of Haiti,” the Clinton Library said.

Clinton presented Carter with the Presidential Medal of Freedom, the nation’s highest civilian honor, in 1999.
