Former Democratic President Jimmy Carter thinks President Trump has a chance at winning the Nobel Peace Prize if he can strike a deal with North Korea.

“If President Trump is successful in getting a peace treaty that’s acceptable to both sides with North Korea, I think he certainly ought to be considered for the Nobel Peace Prize,” Carter told Politico. “I think it would be a worthy and a momentous accomplishment that no previous president has been able to realize.”

Trump is scheduled to sit down with North Korean leader Kim Jong Un on June 12 in Singapore to discuss denuclearization, though Kim has signaled that he may be reconsidering the summit.

Carter said months ago that he was willing to travel to North Korea to negotiate on behalf of the U.S. Instead, Secretary of State Mike Pompeo recently made two trips to the country, bringing back American detainees held by the regime.

In his interview with Politico, Carter dinged the U.S. for its actions isolating North Korea and offered possible solutions to the Trump administration.

“If they’re under constant belief that the United States wants to attack them, even using nuclear weapons — which many Democrats and Republican leaders in our country have mentioned as a possibility — and that we are destroying their economy, and they know that they’re starving to death primarily because the United States withholds food aid, for instance, just giving them surplus food that we can’t ever use, then I can understand how they feel,” he said.

He added: “I think that the next mediator, next negotiator — maybe President Trump, I hope — will reassure them that we’re willing to give up some of those things — the threat of attack on them and to lift the embargo. That would be a cheap price, in my opinion, to pay for a cessation of their nuclear program.”

Carter joins a growing number of Republicans who have called for Trump to win the Nobel Peace Prize for his handling of North Korea.
