"Just landed – a long trip, but everybody can now feel much safer than the day I took office," Trump wrote. "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!"

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

The tweets came one day after Trump and Kim signed a document that says North Korea “commits to work toward complete denuclearization of the Korean Peninsula.”

The agreement also puts an end to the United States’ “war games,” or joint military exercises, with South Korea “unless and until we see the future negotiation is not going along like it should,” Trump said in a press conference Tuesday.
