As President Donald Trump prepared to sit down with North Korean leader Kim Jong Un at a summit in Singapore, members of the Korean-American community on Long Island were hopeful that something positive comes out of the talks.

Rev. Won-Geun Kang, of the Plainview United Methodist Church, said he was very optimistic that Trump and Un would come to an agreement. He also said he remains positive that Un will rid his country of its nuclear arsenal.

The pastor has five sisters living in South Korea. He said they recently called him and shared in his optimism, saying, "Brother, we're going to be reunited with the North soon."

But other Long Islanders of Korean descent weren't nearly as optimistic. Skeptics said they don't see any meaningful breakthrough at the summit because Kim Jong Un is untrustworthy.

Julian Ku is a Hofstra law professor and an expert in international affairs. He thinks a likely outcome is both sides saying they plan to meet again -- and that they have a framework for an agreement that will take time to iron out.

"A nice meeting, happy pictures and an agreement to talk more -- I think that's a reasonable expectation," the professor said. "I think the most important thing that may come out of it will be the media coverage. The feeling that we're no longer on the brink of war and that we're moving in the right direction -- those kinds of things sometimes take on a momentum of its own."
