President Donald Trump declared that North Korea no longer posed a nuclear threat, even though Kim Jong Un hasn’t committed to a timetable for giving up his weapons.

“Everybody can now feel much safer than the day I took office,” Trump said on Twitter shortly after arriving back in Washington. “There is no longer a Nuclear Threat from North Korea.”

Trump and Kim’s summit produced a historic handshake and a joint statement that committed North Korea to “complete denuclearization” without providing any details about how that would happen. U.S. defense analysts have said Kim retains as many as 60 nuclear bombs and a range of missiles, including some he says can strike the U.S.

“Before taking office people were assuming that we were going to War with North Korea,” Trump said in another tweet. “President Obama said that North Korea was our biggest and most dangerous problem. No longer - sleep well tonight!”
