The "preposterous non-offer" from North Korea's Kim Jong Un that President Donald Trump rejected was a "negative-5" on a scale of 1-10, according to former NATO Supreme Commander Adm. James Stavridis.

"I think the North Koreans, particularly the Chairman Kim Jong Un, came to the table with a deal that was just a terrible bargain for the United States," Adm. Stavridis told "The Cats Roundtable" on 970 AM-N.Y. "On a scale of 1 to 10, I would say he brought negative five. It just didn't make any sense."

Kim sought for the U.S. to lift all economic sanctions against North Korea in exchange of dismantling just "one old antiquated nuclear site," but President Trump summoned his inner Kenny Rogers "Gambler," Adm. Stavridis told host John Catsimatidis, knowing "when to hold them, know when to fold them, know when to walk away."

"I think the president made the right move, walking away," Stavridis said.

Stavridis told Catsimatidis he now expects China to "leverage" their work with North Korea into a potential trade deal when President Xi Jinping attends the upcoming Mar-a-Lago summit, saying wants President Trump to resist against falling for in another short-changing proposal.
