Thousands of North Korean soldiers marched in lockstep through the city's main square.
Vice President Mike Pence visited the demilitarized zone between North and South Korea on Monday, stressing that the US's strategic patience with North Korea was over, and that the United States is considering the use of military force.
Their hope is that the White House will focus on pressuring China, Pyongyang's only major ally and biggest trade partner, to redouble its efforts to rein in the regime and prompt North Korea to return to the negotiating table after it abandoned the six-party talks in 2009.
President Trump was asked if he had a message for North Korean dictator Kim Jong-Un over his continued threats of war against the United States and it's allies.
MARGARET WARNER: Mr. Pence also declared again that the USA and its allies will act, unless China its influence to rein in North Korea.
But while Trump tries to force China's hand against North Korea, where their leverage may be been overestimated, he refuses to give an inch on the US's end.
The USS Carl Vinson carrier-led Navy strike group was sent to the Korean Peninsula.
Pence's advisers said the vice president would make the case to Abe and Aso that the US rejection of the Trans-Pacific Partnership, or TPP, under Trump did not signal a USA withdrawal from trade and economic development in the region.
The North Koreans just issued their own warning too.
Pyongyang again said it has sent letters demanding its own hearing at the Security Council for alleged U.S. abuses, but they have been ignored by a council which has seen numerous council resolutions violated by North Korean missile and nuclear tests.
Han said an "all-out war" would result if the U.S. took military action. "If the USA is planning a military attack against us, we will react with a nuclear pre-emptive strike by our own style and method".
Ahn was speaking in a conservative stronghold at a time when North Korea has ratcheted up regional tensions with threats of another nuclear or missile test. -South Korean military exercises being staged now are the largest-ever "aggressive war drill" aimed at his country, formally the Democratic People's Republic of Korea.
Pence's Asia tour came amid increasing tensions and heated rhetoric on the Korean Peninsula.
"All options are on the table" in pushing for an end to Pyongyang's nuclear programme, Pence said, adding that the era of USA "strategic patience" in dealing with the regime was over. A full analysis of the missile's possible maximum range is hard given that there has not been a successful test so far.
The new KN-15 designation was created to distinguish it from the KN-11, North Korea's solid-fueled, submarine-launched missile, which the country tested last summer.
At the outset of their meeting, Pence reiterated to Abe his statement in South Korea that the United States has run out of patience with Pyongyang's moves.
"Neither candidate has suggested that they'd like to break relations with the United States", or even fundamentally alter the US-South Korean alliance, Kim says. "We have to be honest about where our trade relationship is falling short", said Pence, adding the Trump administration would work with businesses on reforms. Reuters recently reported that the latest calls from Chinese diplomats to North Korea had gone unanswered.
MARGARET WARNER: The dueling rhetoric came after North Korea's ballistic missile launch on Sunday, which USA officials say blew up within seconds.
The failed missile launch was rumored to be sabotaged by the US, but Fleitz said he thinks it more likely demonstrates that even while North Korean technology is advancing, it's still inadequate.
