Standing before a B-2 stealth bomber and a vast USA flag, Donald Trump on Friday (Sept 15) lashed out at North Korea warned that advanced U.S. weaponry could make the souls of America's enemies "crumble".
Trump has said the U.S. and its allies will not be intimidated by the reclusive nation.
Last week, Trump and his top national security advisers said that there are military options available despite doubts from some experts.
During the 25-minute call, Trump and Moon condemned the latest missile launch by North Korea, pledging to work with the global community to implement the latest UN Security Council resolution.
North Korea fired an intermediate range ballistic missile over Japan on Friday, marking the second highly provocative missile launch in less than a month.
The UNSC referred to the latest launch as a "manifest violation" of Security Council resolutions that comes less than two weeks after the DPRK conducted a test of a nuclear device on September 3, and only three days after the Security Council unanimously adopted fresh sanctions against the country.
A top US national security official says President Donald Trump will work to build business ties between the USA and other nations during the United Nations General Assembly next week. New U.N. sanctions cut oil exports to North Korea. "They should do more to find effective ways to resume dialogue and negotiation", he said, while adding that China would never accept North Korea as a nuclear weapons state.
". Additional provocations will only further isolate the country (North Korea) diplomatically and economically, and will eventually lead down the path of its own collapse".
US Secretary of Defence James Mattis spoke over phone with his Japanese counterpart Itsunori Onodera following the latest North Korean missile launch, the Pentagon said.
"I don't think that he'll stray too much outside of the boundaries of that", Collins said.
North Korea's ambassador to the United Nations Han Tae Song, however, declared that Pyongyang condemns this "latest illegal and unlawful UN Security Council resolution". The North accuses the United States, which has 28,500 troops in South Korea, of planning to invade and regularly threatens to destroy it and its Asian allies.
