Amb. Nicholas Burns, Amb. Wendy Sherman and Amb. Chris Hill join Morning Joe to discuss the president's summit in Singapore with North Korean leader Kim Jong Un and the president's press conference following the summit.

While President Donald Trump prepares for his planned June 12 summit with Kim Jong Un, questions abound about the historic talks. When it comes to North Korea’s nuclear program, what is really on the table? What’s the United States willing to give up in return? And, most crucially, what would a successful deal with North Korea look like?

We should all be glad that Kim Jong Un, the leader of North Korea, and Moon Jae-in, the president of South Korea, had a positive summit — and that Kim literally took a historic step into the South, as did Moon, briefly, into the North. Dialogue is certainly better than a march to war. That said, we all need to keep our expectations in check.

John R. Bolton, President Trump’s new national security adviser, has never met a war he didn’t want.

The Trump administration is right that Iranian behavior destabilizes the region, but wrong when it says that such behavior contradicts the “spirit” of the agreement and that he is therefore justified in refusing to certify Iran’s compliance. In fact, Iran’s troubling foreign policy is precisely why the deal was necessary in the first place: An Iran armed with a nuclear weapon would be far more threatening to regional and global security.

North Korea is the most difficult and dangerous challenge facing the U.S. today. Pyongyang is on the path to developing a nuclear missile delivery system that could strike the United States. In fact, since 2013, the country has followed Kim Jong Un’s version of his grandfather’s “byungjin policy”, which stipulates that simultaneous nuclear expansion and economic development are necessary for the regime’s survival. North Korea shows no signs of abandoning its nuclear ambitions, which pose a mounting strategic threat to the Asia-Pacific region; the alternatives to a peaceful resolution are even more harrowing. Denuclearization of the Korean Peninsula will require all stakeholders in Northeast Asia—South Korea, Japan, the United States, and especially China—to cooperate on measures that could help precipitate North Korea’s return to the negotiating table.

Although Jen Palmieri, Hillary Clinton’s communications director, acknowledged that the campaign should have let the press know sooner that Secretary Clinton was fine, following her leaving the 9/11 memorial for health reasons on Sunday, working women have known for decades that even when you’re sick, you work. Mothers joke that they aren’t allowed to get sick, and advertisers rake in profits for cold and flu relievers that allow moms to go on doing their jobs. And women in the workplace, often judged for how strong or weak they are, regularly come to work even when they should be home in bed—even when society should allow for rest and recovery.

I learned this lesson early in life. During my early professional years, somehow my body knew it had to wait to get sick until it was time for annual leave. So I ended up spending my vacation time nursing bad sinus infections or flu, before flu shots. Later in my professional career, I simply learned to soldier on, no matter what.
