"The coming few months will give us a better indication as to whether [this] was an expensive photo opportunity or a positive breakthrough", said Patrick Cronin, the top Asia security expert at the Center for New American Security in Washington. We also agreed to vigorous negotiations to implement the agreement as soon as possible, and he wants to do that.
Critics have said the encounter between Trump and Kim was more style than substance, producing a document short on details about the key issue of the North's atomic weapons.
In his post-summit press conference, Trump made the surprise announcement that the United States would halt joint military exercises with its security ally Seoul - something long sought by Pyongyang, which claims the drills are a rehearsal for invasion. The agreement provided no timetable for giving up as many as 60 nuclear bombs and a range of missiles, including some that he says can strike the American homeland. And so do the North Koreans.
"The World has taken a big step back from potential Nuclear catastrophe!"
Trump has sought to portray his unprecedented meeting with Kim as a significant accomplishment that has made the world less vulnerable to the North's nuclear arsenal.
In the joint statement, North Korea only agreed to "work toward" denuclearization.
He said he was confident Pyongyang understood the need for verification that it was dismantling its nuclear programme.
"Pyongyang will read this as a concession that its nuclear and missile advancements purchased weaker language on denuclearization, " Mount said. North Korea is a real and present threat.
Pompeo will then travel to Beijing, North Korea's main diplomatic ally.
"Countries like Iran and Cuba and other two-bit rogue regimes don't have nuclear weapons, yet", Cotton told Hugh Hewitt.
U.S. Secretary of State Mike Pompeo arrived at Osan Air Base south of Seoul from Singapore early Wednesday evening.
Pompeo said Trump was alluding to the fact that it was the first time a sitting USA president had met with Kim, adding that both leaders had a "blunt conversation" about the need for the communist state to rejoin the world community.
However this stock phrase, favored by Pyongyang, stopped short of longstanding United States demands for North Korea to give up its atomic arsenal in a "verifiable" and "irreversible" way.
North Korea's neighbors have grown accustomed to living with a nuclear North Korea.
Joint U.S. and South Korea military exercises occur regularly on the Korean Peninsula and have long angered North Korea, with Mr. Kim - like his father and grandfather before him - having called the drills a preparation for invasion of the North and seized on them as an impetus for hurling threats at Washington and Seoul.
During his post-summit press conference, Trump admitted that he may be wrong about Kim's willingness to denuclearize.
