U.S. President Donald Trump and North Korean leader Kim Jong-un have agreed to meet in Singapore on June 12, signaling a historic summit and the first meeting between a sitting U.S. president and a North Korean leader. The date and location were finalized following a meeting between North Korea and Secretary of State Mike Pompeo.

“For decades, we have been adversaries,” Pompeo said to CBS News. “Now we are hopeful that we can work together to resolve this conflict.”

Although Trump has warned of potentially unsuccessful talks at the summit, his optimistic attitude on Twitter suggests a beneficial meeting, especially after the release of American prisoners Kim Dong Chul, Kim Hak-Song and Tony Kim from North Korea on May 10 according to CNN.

“We are starting off on a new footing — I really think we have a very good chance of doing something very meaningful. A lot of very good things have happened,” Trump said in an interview with CNN following the release of the prisoners.

However, tensions arose between the two nations, culminating in a cancellation by Trump on May 24 after insults were exchanged between North Korea and the U.S.

In a sudden change of events, South Korean President Moon Jae-in traveled to meet with Kim in order to ensure that the summit would still occur. Throughout the end of May, North Korean officials such as Vice Chairman of North Korea Kim Yong Chol will rebegin laying the foundations with U.S. officials like Pompeo for the June 12 summit.

“What appears to be a hopeful meeting of diplomatic minds intent on resolving six decades of strife with a buildup behind it that seemingly differentiates it from previous, failed attempts towards the same goal, whether between the Koreas or the North and the U.S., is only that: hopeful,” sophomore David Jang said. “Such a meeting’s degree of achievement will only be decided by time; cooperation is ideal, mutual understanding desired, whilst added tensions are detrimental to all parties.”

Many experts warn that Kim’s plans of complete denuclearization are far from sincere, according to Business Insider. Regardless, the fact that the two controversial figures are even meeting serves as a large stepping stone in a more peaceful future. Both sides seem willing to concede some of their personal preferences in hope of world peace and easing tensions between two powerful nations.
