"President Trump offered Kim Jong-un a different path to the world stage. A path not even thought of by our former leaders — one of economic prosperity instead of failed nuclear destruction," Rep.

"While there is a long way to go to achieve verified denuclearization, I look forward to seeing North Korea become a free, prosperous and demilitarized state," he continued.

"However, if Kim Jong-un throws away this opportunity, it will mean the military destruction of his country and his death," Reed added.

Reed, a centrist Republican and member of the bipartisan Problem Solvers Caucus, issued his statement hours after Trump and Kim met for a historic summit in Singapore.

The two leaders met face-to-face on Tuesday, joined only by translators, followed by expanded meetings with members of their respective administrations.

After hours of discussions, the two men signed an agreement committing the United States to unspecified “security guarantees” in exchange for a denuclearized Korean Peninsula. The document did not include specifics on the timeline or nature of denuclearization, however.

“I think both sides are going to be impressed with the result,” Trump told reporters. “We’re going to take care of a very big and very dangerous problem for the world.”

Trump also announced that the U.S. would call off military exercises with South Korea while negotiations continue with the North.

Trump's allies have praised the president for bringing Kim to the negotiating table, and expressed cautious optimism about the prospects of a denuclearized North Korea.

Critics, meanwhile, have argued that Trump praised the North Korean strongman on the international stage and granted him legitimacy while receiving few concrete concessions in return.
