'Sleep well tonight!' Trump claims nuclear threat from North Korea is over in pair of early morning tweets

President Donald Trump promised he had solved the nuclear problem with North Korea in a series of tweets after arriving back in Washington, D.C.

The president met earlier this week with Kim Jong-un in Singapore, where he promised to lift sanctions and end joint military exercises with South Korea in exchange for the eventual denuclearization of North Korea.

"Just landed - a long trip, but everybody can now feel much safer than the day I took office," Trump tweeted. "There is no longer a Nuclear Threat from North Korea. Meeting with Kim Jong Un was an interesting and very positive experience. North Korea has great potential for the future!"

Trump left before negotiating details of North Korea's denuclearization, but he claimed victory and took a shot at his predecessor.

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