North Korea launched a series of ballistic missile tests on Sunday, raising the stakes and putting pressure on President Biden. The missile was fired at 7:52 a.m. from the North Korean province of Jagang, near China, and traveled across the country before crashing into the ocean off the east coast. A total of seven missile tests this month.

President Moon Jae-staff called the projectile an intermediate-range ballistic missile and said the inspection violated UN Security Council regulations. It was the North’s most powerful launch since November 2017, when it tested an intercontinental ballistic missile that traveled far higher.

Mr. Moon cautioned that North Korea’s self-imposed moratorium on long-range ballistic missile tests, established in 2018, may be soon lifted. Mr. Kim said last week that his officials would soon begin such tests.

In reaction to the Sunday launch, Mr. Moon said at a meeting of his National Security Council, “North Korea has gone close to abandoning its moratorium.”

“North Korea should stop raising tensions and accept offers from South Korea and the US to reopen talks,” he said.

It encouraged the North Koreans “to refrain from such destabilizing acts,” despite the fact that the launch presented no immediate threat to the US or its allies. Japan “seriously” criticized the check, said Chief Cupboard Secretary Hirokazu Matsuno in Tokyo.

A decade ago, there were more missile tests in January than any other month since Mr. Kim took power a decade ago. Sunday’s launch was the third in the last week.

The North’s nuclear and missile capabilities have been on Mr. Kim’s radar since his direct negotiations with then-President Donald J. Trump faltered in 2019. Rather than continue discussions “without preconditions,” he has instructed his officials to prepare for “long-term confrontation” with the US.

Mr. Moon and South Korean observers compared the present examinations to 2017. That year, the North gradually increased its weapons tests, from short-range missile launches to intermediate-range ballistic missile tests. Finally, it looked at three ICBMs and mentioned a hydrogen bomb.

For this, Trump persuaded the UN Security Council to impose further sanctions on North Korea, threatening it with “fire and fury.” He met Mr. Kim three times privately, but their private diplomacy failed to halt North Korea’s nuclear development or relieve sanctions.

“The pattern has repeated itself: North Korean provocations, followed by a round of discussions, their failure, and a diplomatic pause,” said Cheon Seong-whun, former director of Seoul’s Korea Institute for Nationwide Unification. “North Korea is currently escalating tensions with missile provocations.”

Its goal is to force the US and its allies to accept its nuclear arsenal, ”he said.

North Korea last tested an intermediate-range ballistic missile, the Hwasong-12, in September 2017.

The missile fired on Sunday reached a height of 1,242 miles and covered a distance of 497 miles, according to South Korean defense officials. North Korea routinely misses tests of intermediate and long-range missiles at an acute angle.

That prevents them from flying over Japan, which Tokyo, Washington, and their allies may find extremely provocative. These missiles might cover more distance if launched on standard ballistic missile trajectories.

The flight data from Sunday’s launch matched that of a Hwasong-12 intermediate-range ballistic missile fired by North Korea in May 2017. This missile flew 1,310 miles and landed in the sea 480 miles from the launch point.

The Importance of North Korea’s Missile Assessments

Resolutions In 2017, North Korea inspected three intercontinental ballistic missiles and conducted a nuclear test. The UN imposed sanctions, and Pyongyang temporarily halted nuclear and long-range missile tests.

Later that year, North Korea conducted provocative tests of the same type of missile, firing them over Japan. In these missile tests, the missiles traveled up to 2,300 miles before landing in the Pacific. So they’d be able to get inside US bases on Guam with that.

In 2017, the North evaluated an ICBM from 2,796 miles up and covered 596 miles. After that, North Korea claimed their ballistic missiles could target elements or the entire US.

He and other experts said they didn’t anticipate the North testing another ICBM immediately. They predicted escalating tensions with a series of increasingly daring strikes.

A professor at the College of North Korean Research in Seoul said it was “only a matter of time” before the North fired an ICBM once more. “North Korea believes Washington ignores it despite its recent missile tests,” he said. “It’s increasing its pressure on Washington, scheduling an ICBM test dependent on Washington’s response.”

The recent launches surprised some local observers who expected the North to back off before the next Winter Olympics in Beijing. The North’s only ally is China.

Mr. Kim may have used the deteriorating US-China and Russian ties to sneak in weapons checks. Asked by Washington to apply further penalties to North Korea for the current examinations, both Beijing and Moscow blocked the move.

Analysts say the tests allow the North to strengthen its missile capabilities while also pressuring the Biden administration to be more accommodating.

Analysts stated Mr. Kim also sought to boost domestic morale as his government prepared for two major events—the 80th anniversary of his father’s birth in February and the 110th anniversary of his grandfather’s birth in April. Each had led North Korea before him.

According to North Korean official media, Mr. Kim visited “a munitions production plant constructing an important military system” on Friday.

Professor Yang said the North will keep testing missiles until May, when whoever wins the March presidential election in South Korea takes office. “It will create an extreme situation before transferring to a new section of diplomacy with Washington and the next government in Seoul,” he stated.
