GOP Rep. Tom Reed (N.Y.) warned on Tuesday that if North Korean leader Kim Jong Un were to walk back agreements made with President Donald Trump it would “mean the military destruction of his country and his death.”

“President Trump offered Kim Jong-un [sic] 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,” Reed said, according to The Hill.

“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’s remarks come just after President Trump and Kim met to discuss denuclearization and diplomatic relations between the U.S. and North Korea.

The two leaders met at the Capella Hotel on Sentosa Island, just off the southern coast of Singapore, at 9 a.m. local time. The meeting — and the handshake that has drawn so much attention — was a historic first between leaders of the two nations.

After the meeting, both men signed a document that reportedly details “security guarantees” granted by President Trump in exchange for North Korea’s commitment to the “complete denuclearization of the Korean Peninsula.”

President Trump did not give a timeline for when the Kim regime would begin the denuclearization process, though he stated in a press conference after the meeting that it would begin “very quickly.” He also stated that the U.S. would halt “war games” with South Korea during the negotiation process.

Both leaders appeared to be planning for a second meeting, something officials said President Trump was receptive to and could host at his Mar-a-Lago resort in Florida in the days leading up to the summit.
