Deputy national adviser K.T. McFarland briefed the president on the failed missile launch.
"The missile blew up nearly immediately".
A total of 56 missiles of 10 different types were displayed, culminating in enormous rockets on articulated trailers and on 16-wheeler vehicles.
The attempted launch Sunday in North Korea came hours before Vice President Mike Pence, briefed about the situation while aboard Air Force Two, was set to arrive in South Korea.
Pence is travelling to South Korea to hold talks with the country's leadership. "It has happened in the past, and the last few days have shown us that the Korean War not over".
The extended-range Scud missile in that earlier launch suffered an in-flight failure and fell into the sea off North Korea's east coast, according to USA imagery and assessments. An official from South Korea's Defense Ministry couldn't immediately confirm whether the rocket was a new ICBM.
In the end, however, they settled on a policy that appears to represent continuity.
Mr Choe declared that the North was a "powerful nuclear-armed state in the Orient and Asia's leader in rocketry". "The national security interest of the United States in this case is the threat of the regime to us and our allies in the region and so our focus is on that".
North Korean leader Kim Jong-Un Saturday saluted as ranks of goose-stepping soldiers followed by tanks and other military hardware paraded in Pyongyang for a show of strength with tensions mounting over his nuclear ambitions.
A clearly rattled China, under pressure from Trump to prevent any North Korean provocation, said the situation had reached breaking point.
"Trump is always making provocations with his aggressive words", Han Song Ryol said. China is North Korea's lone major ally but has spoken out against its missile and nuclear tests and has supported United Nations sanctions.
Tension had escalated sharply in the region amid concerns that the North may conduct a sixth nuclear test or a ballistic missile test launch around Saturday's birth anniversary of founding father Kim Il Sung that it calls the "Day of the Sun".
While Mr Trump has put North Korea on notice that he will not tolerate any more provocation, USA officials have said his administration is focusing its strategy on tougher economic sanctions.
Lastly, the third scenario would see North Korea doing the pre-emption, either as Vinson steams intolerably close to the Korean theatre of operations or while it is loitering around the peninsula at the Trump administration's behest. On Tuesday he declared ominously that "North Korea is looking for trouble".
Kim Jong Un's government has pledged "a big and important event".
"The fact is, this regime is never going to voluntarily give up nuclear weapons, they're the ace in the hole", he said.
Beijing has long opposed dramatic action against the North, fearing the regime s collapse would send a flood of refugees across its borders and leave the U.S. military on its doorstep.
"We're prepared to respond to an all-out war with an all-out war and we are ready to hit back with nuclear attacks of our own style against any nuclear attacks", Choe Ryong-Hae said in a speech at a ceremony before a large military parade started, which was broadcast live by the North's Korean Central TV.
Pyongyang has also expressed anger over the ongoing annual spring military exercises the US holds with South Korea, which it considers a rehearsal for invasion.
He then walked up to a podium and clapped with senior government officials to address the thousands of soldiers and a massive crowd taking part in the parade in capital Pyongyang.
The rockets carried on articulated trailers appeared to be longer than the North's existing KN-08 or KN-14 missiles, analysts said. The United States, South Korea and other countries have vowed to apply more pressure on the North, but so far nothing has worked to stop Pyongyang's nuclear program.
North Korea, still technically at war with the South after their 1950-53 conflict ended in a truce but not a treaty, has on occasion conducted missile or nuclear tests to coincide with big political events and often threatens the United States, South Korea and Japan.
