Success of second Trump-Kim summit will lie in the details

Where it stands: Trump and Kim each face immense pressure, both international and domestic, to make progress.

• Trump needs to earn political trust back in Washington to continue negotiating with North Korea. His strategy so far has been to convince Kim that North Korea’s denuclearization would bring the country a “bright future.”
• At the same time, Trump must address Kim’s concerns about whether any agreement reached with his administration will withstand the Democrat-controlled House and survive the post-Trump era.

Between the lines: Successful diplomacy sometimes entails purposeful ambiguities, and the ambiguities of the first Trump-Kim summit might indeed have been strategic. At this critical juncture, however, a failure on Trump’s and Kim’s part to commit to defined objectives could hurt the bilateral relationship.

The bottom line: Trump and Kim need support more than ever to advance their diplomatic endeavors. While spectators have good reason to be skeptical, and one can only be cautiously hopeful with North Korea, a return to confrontation or "strategic patience" is in no one’s interest.
