North Korea, in 2016, conducted two nuclear tests and numerous missile launches in its quest to develop a nuclear weapons system capable of hitting the United States mainland.
The platform tested in North Korea's first missile launch since Trump took office was similar to Musudan intermediate-range missiles launched from the same site on previous occasions.
'HOLY MOLY! It was fascinating to watch the flurry of activity at dinner when the news came that North Korea had launched a missile in the direction of Japan.,' wrote DeGazio. It employs a solid-fuel system that is quicker for launching than the liquid-fuel system employed in the Musudan.
North Korea has grown more and more aggressive as it glides along the path of nuclear weapons development.
Gardner also sent a letter to Trump on Friday, a day before the North's missile launch, calling for sharper sanctions on Pyongyang; greater pressure on China, including secondary sanctions; and stronger trilateral security cooperation among the U.S., South Korea and Japan.
North Korea has conducted two nuclear tests and several missile-related tests since early a year ago and was seen by experts and officials to be making progress in its weapons capabilities.
White House press secretary Sean Spicer released a statement in reference to North Korea.
The U.N. Security Council is expected to hold consultations on the missile test, diplomats said at the U.N. headquarters in NY.
The UN Security Council is set to meet to discuss the latest breach of its resolutions.
South Korea convened an emergency national security meeting Sunday morning in response to the launch.
It called on all United Nations members to implement the six sanctions resolutions adopted by the council since 2006. South Korean military says the missile flew east towards the Sea of Japan. Another official, speaking on the condition of anonymity, added that the test launch was probably of not an intercontinental ballistic missile.
"Road-mobile allows it to hide, to evade detection and to be able to launch with little notice, " Davis said.
Mr Trump was entertaining Japanese Prime Minister Shinzo Abe at the time of the missile launch and the pair later released a joint statement condemning the action.
Trump has previously pledged to be tougher on the North Koreans than previous administrations. But he has not has yet defined a strategy for dealing with that.
North Korea has been under United Nations sanctions since 2006 over its nuclear and ballistic missile tests. It already has the technology to make warheads small enough to fit on medium-range Nodong missiles, which can reach Japan and South Korea.
