Meghan McCain, conservative co-host on "The View," took President Donald Trump to task over his "buddy-buddy" behavior with North Korean leader Kim Jong Un during their Tuesday summit.

What's some background?

The historic summit between Trump and Kim happened in Singapore after months of speculation as to whether it would actually happen. It was preceded by months of nuclear war fears, exacerbated by both men's tough-talking rhetoric.

Regardless, the summit concluded with a signed statement in which the North Korean leader "reaffirmed his firm and unwavering commitment to complete denuclearization of the Korean Peninsula" and which "Trump committed to provide security guarantees to the DPRK."

What did she say?

During Tuesday's show, McCain lauded the summit but lashed out at the closeness of the two men as she and the other co-hosts discussed whether the public could take Trump and Kim at their words of denuclearization and peace.

"I had a really big problem with the American flag and North Korean flag next to each other as the backdrop," McCain said. "We are not the same."

"This is a totalitarian, Communist dictator in the same vein as Hitler: murder, enslavement, torture, imprisonment, sexual violence, starvation, forced abortions, political/racial persecution," she said of the North Korean leader. "It is a completely and utterly, the closest thing to Hitler's Germany that exists in our time."

"My problem is how far it went with the buddy-buddy and there was no talk whatsoever of the human rights violations going on in that country," she noted.

After the hosts went back and forth about the preparations for the meeting, with some of the hosts saying that Trump was ill-prepared for such a summit, McCain underscored the historic importance of the two men meeting.

"We can’t undersell how historic it is, though," McCain cautioned. "Just even getting [Kim Jong Un] to the table is — I mean I never thought I would see this in my lifetime whatsoever. So I give Trump credit for this."
