"The president's consistent message will emphasize three goals: first to promote peace, second to promote prosperity, and third to uphold sovereignty and accountability", White House national security adviser H.R. McMaster told reporters at the White House on Friday (September 15).
Speaking to military personnel at Joint Base Andrews in Maryland on Friday en route to his New Jersey golf club, Mr Trump said that North Korea had "once again shown its utter contempt for its neighbours and the entire world community".
North Korea launched what appeared to be an intermediate-range ballistic missile over northern Japan early Friday (local time), defying worldwide calls to halt its provocations.
Haley repeatedly said the latest package of North Korea sanctions unanimously passed by the Security Council is significant, calling it a "massive sanctions package".
The top US officials said that it will take time to see how the latest round of U.N. Security Council resolutions might change North Korea's behavior, but that after these measures there's not much more that the diplomatic body can do to punish North Korea.
"What we are seeing is they continue to be provocative, they continue to be reckless".
The UN Security Council imposed the "strongest sanctions ever" on North Korea Monday, putting intense pressure on the regime.
"We have strangled their economic situation", she said. "So what we have to do is call on all nations, call on everyone to do everything we can to address this global problem short of war". "Now, it's not what we prefer to do".
In her opening remarks, Haley made sure to savage North Korea for its repeated nuclear and ICBM missile tests.
The last set of sanctions included restrictions on North Korea's oil imports and a ban on its textile exports.
