Analysts around the world are reacting to the abrupt end of President Trump and North Korean leader Kim's negotiations in Hanoi.
"It is little wonder these negotiations broke down after Trump has spent more time in office blowing up nuclear treaties than building them," said Akira Kawasaki of the International Committee to Abolish Nuclear Weapons’ International Steering Group.
"We need a real plan rooted in the international community and treaties like the Treaty on the Prohibition of Nuclear Weapons, which the Koreas could join tomorrow and begin the disarmament process with legitimacy."
Van Jackson, author of "On the Brink: Trump, Kim, and the Threat of Nuclear War," said that the US should have waited to hold the summit until progress had been made "at the Biegun level," referring to the US negotiator on the Korean Peninsula, Steve Biegun.
"This is why you don’t have leader summits disconnected from real negotiations. Even if the summit was 'successful' by the standards of the administration and its surrogates, it would’ve failed to address North Korea’s nuclear arsenal, which was never on the table in talks in recent months."
He added that "now it appears that even the very low bar that was set was not crossed."
