​WASHINGTON – Democratic presidential candidate Amy Klobuchar said diplomacy with Kim Jong Un isn’t as easy as “bringing a hot dish over the fence to the dictator next door.”

Klobuchar, a U.S. senator from Minnesota, wasn’t ready to give President Trump credit for his Sunday meeting with Kim in the DMZ, in which Trump became the first sitting U.S. president to step foot in North Korea.

“I don’t think we know if it worked until there’s results and we’ve seen history here, especially in this case where Donald Trump announced the summit and nothing really comes out of it,” ​Klobuchar said​ in an interview on CNN’s “State of the Union.”

She said she wanted to see the dialogue work.

“We want to see a denuclearization of the Korean peninsula, a reduction of these missiles, but it’s not as easy as just going and, you know, bringing a hot dish over the fence to the dictator next door,” the folksy senator said.

A “hot dish” is a type of Minnesota casserole, often made with meat, potatoes and canned vegetables.

“This is a ruthless dictator and when you go forward you have to have clear focus and a clear mission and clear goals. And that has been our problem so far,” Klobuchar continued.

Klobuchar – who was one of the 20 Democrats who made the debate stage last week in Miami – also took issue with how Trump handled his G20 meeting with Russian leader Vladimir Putin.

“Toughness is not just saying things by tweet, toughness is results and standing true to our country,” she said. “At the same G20 summit, the president was coddling, again, Vladimir Putin. Making jokes about getting rid of journalists to a man who has been involved with thugs who have killed and poisoned journalists and human rights activists.”

Klobuchar also hammered Russia for meddling in the 2016 U.S. election and criticized Trump for “making jokes” about it with Putin.

“Russia did that,” she said.
