SEOUL, South Korea — North Korea fired two short-range ballistic missiles off its east coast on Wednesday, the South Korean military said, the North’s second weapons test in less than a week.
The missiles were launched from near Wonsan, a coastal town east of Pyongyang, the North Korean capital, the South Korean military said in a brief statement. They flew 155 miles to the northeast, reaching a height of 18 miles, before splashing into the sea, it said.
South Korean officials declined to offer further details, pending analysis of flight and other data together with their United States allies.
“North Korea’s recent series of missile tests does not help efforts to ease tensions on the Korean Peninsula and we urge the North to stop this type of act,” the South Korean military said.
That was the first time South Korea had formally accused the North of testing a ballistic missile since November 2017, when the North launched the Hwasong-15, an intercontinental ballistic missile capable of reaching the mainland United States. United Nations resolutions forbid North Korea to launch ballistic missiles of any kind.
Japan said the North Korean projectiles launched Wednesday had not landed in its territorial waters, indicating that they were short-range weapons.
North Korea’s resumption of weapons testing has come amid stalled efforts to resume talks with the United States on ending its nuclear weapons program.
President Trump met with the North’s leader, Kim Jong-un, in the Demilitarized Zone on June 30, and both leaders agreed to resume staff-level dialogue between their governments. But such talks have yet to take place.
Weeks before Mr. Kim met with Mr. Trump in Singapore in June last year in the first-ever summit meeting between North Korea and the United States, Mr. Kim announced a moratorium on his country’s nuclear and intercontinental ballistic missile tests. Mr. Trump has since repeatedly touted the absence of such tests as his biggest diplomatic achievement in dealing with Mr. Kim.
With North Korea’s latest tests involving short-range missiles, Mr. Kim did not abandon his moratorium. But they violated the United Nations Security Council resolutions that bar the country from developing or testing ballistic missile technologies, South Korean officials said.
Mr. Trump downplayed the significance of the North’s recent missile tests last Thursday, calling them “smaller ones” and repeating that he was still getting along “very well” with Mr. Kim.
“My relationship with Kim Jong-un is a very good one, as I’m sure you’ve seen,” Mr. Trump told reporters on Tuesday. “I like him; he likes me. We’ll see what happens.”
The Singapore meeting ended with a vague agreement in which Mr. Trump committed to building new relations and providing security guarantees for North Korea in return for Mr. Kim’s agreement to “work toward complete denuclearization of the Korean Peninsula.”
But when the leaders met again in Hanoi, Vietnam, in February, they failed to agree on how to implement their earlier deal.
The Hanoi talks collapsed when Mr. Kim demanded that Washington lift all major sanctions against his country in return for the dismantling of its nuclear complex in Yongbyon, north of Pyongyang. Mr. Trump insisted on a more comprehensive breaking up of the North’s nuclear programs, including its nuclear weapons and missiles.
Mr. Kim has since said he would give Washington until the end of the year to return to the negotiating table with “new calculations.”
“This type of saber rattling is not threatening, but rather is intended to get the attention of North Korea’s more powerful neighbors,” Daniel L. Davis, a senior fellow with the Defense Priorities research institute in Washington, said by email about the Wednesday tests. “Kim Jong-un wants to negotiate and signal his ability to take actions the U.S. and others don’t like in an effort to speed up diplomacy.”
“There’s an opening to negotiate for freezes and potentially rollbacks in exchange for limited sanctions relief,” Mr. Davis added. “But unless Washington is willing to make such trade-offs and normalize relations, expect Kim to continue developing weapons and testing them.”
North from Syria, along the borders of Eastern Europe and rounding the Arctic Circle to the east, Russia has built a ring of air defenses that threaten the reach of the U.S. military, forcing Washington to rethink its place as the world’s undisputed air power.
Russia’s S-400 antiaircraft missile system, a nettlesome and potentially deadly aerial shield, is changing the calculus of the U.S. and its allies in potential hot spots, beginning with its deployment in Syria.
Radar employed by the S-400, which Russia claims can detect the latest stealth aircraft, casts a net around western Syria that stretches from Turkey to the Mediterranean Sea to Israel.
Proliferation of the S-400 system demonstrates how Russia is also investing heavily in traditional military firepower.
.. “We have to understand that the period of U.S. absolute dominance of the air is over,” said Elbridge Colby, the director of the defense program at the Center for a New American Security, a nonpartisan defense think tank.
The Pentagon acknowledged that S-400 batteries in Syria have forced adjustments to coalition air operations, but it contended the U.S. in general still maintains freedom of movement in the air. “We can continue to operate where we need to be,” a U.S. defense official said.
.. Russia is “fielding military capabilities designed to deny America access in times of crisis and to contest our ability to operate freely,” a report said. “They are contesting our geopolitical advantages.”
A bipartisan commission established by Congress to evaluate President Trump’s defense strategy echoed those fears in a paper released in November. Russia, the commission concluded, was “seeking regional hegemony and the means to project power globally.”
.. Moscow isn’t eager to confront U.S. forces head-on: Russia has a military budget about a 10th the size of the Pentagon’s. Despite Russia’s intervention in Syria and invasion of Crimea, its air force and navy capabilities fall far short of the U.S. and China’s military.
In Syria, more Russian army personnel have been killed in plane crashes than enemy fire, according to official data. Russia’s sole aircraft carrier, the Admiral Kuznetsov, is being overhauled. In October, a crane fell on the vessel, causing serious, possibly irreparable damage to the carrier.
The S-400’s guided missiles are intended to give Russian President Vladimir Putin a lethal threat against Western military intervention should a crisis erupt on Russia’s European borders, in the Middle East or North Korea.
The presence of the S-400 in Syria has been an effective sales tool, drawing interest among both American foes and allies. Purchases by China and India, as well as prospective deals with Turkey and Saudi Arabia, have raised alarms among officials in Washington and at the North Atlantic Treaty Organization.
By selling the S-400 to other countries, Russia spreads the cost of limiting U.S. forces.
“Russia doesn’t want military superiority, but it has ended the superiority of the West or the U.S.,” said Sergey Karaganov, a foreign-policy adviser to Mr. Putin. “Now, the West can no longer use force indiscriminately.”
.. The Pentagon said Russian measures have yet to change America’s position.
“The U.S. remains the pre-eminent military power in the world and continues to strengthen relationships with NATO allies and partners to maintain our strategic advantage,” said Eric Pahon, a Pentagon spokesman. “The U.S. and our allies have quite a few measures at our disposal to ensure the balances of power remain in our favor.”
.. Following the Sept. 11 terrorist attacks, the U.S. used its air superiority against foreign governments considered a threat. Afghanistan, Iraq and then Libya fell into the crosshairs.
In 2010, Mr. Putin announced a plan in to modernize Russia’s military, saying his nation would spend the equivalent of $650 billion over a decade. The plan included replacement and upgrades of aging Soviet antiaircraft and antiship defenses.
.. Russia’s preoccupation with defense is a product of its history, spanning past invasions by Napoleon Bonaparte’s army in the War of 1812 to Nazi troops during World War II.
“The Russian military is configured very differently from expeditionary powers like the United States,” said Michael Kofman, a research scientist at CNA, a nonprofit research group in Arlington, Va. “It’s not meant to mirror powers like the United States, it’s meant to counter them.”
Buyers of the S-400 face possible U.S. sanctions under a 2017 law that penalizes allies that do business with the Russian defense industry.
China received an S-400 shipment last year, and its Equipment Development Department, which oversaw the purchase, was sanctioned in September.
India agreed in October to a $5 billion-plus deal for the S-400 antiaircraft system. It hopes to evade sanctions, saying that as a U.S. security partner it can counterbalance China’s growing power. It is unclear whether Saudi Arabia’s deal with Russia will be completed because of likely U.S. pressure.
The Pentagon has objected to Turkey’s planned S-400 purchase, saying it would give Russia too close a view of NATO operations. Antiaircraft missile systems typically receive data from satellites as well as aircraft to detect attacks. Integration of the S-400 system on Turkish bases also would give Russia insight into radar-evading F-35 combat jets, U.S. officials said.
.. The S-400 hasn’t been tested in battle but on paper it outperforms the comparable U.S.-made Patriot system. Sales to China and India, along with prospective deals with Turkey and Saudi Arabia, have raised alarms in the West.
.. Turkish officials said they need the antiaircraft system to shield the southern border with Syria. Washington installed U.S.-operated Patriot missiles in southern Turkey in 2013, after Syrian armed forces shot down a Turkish jet fighter killing two. The systems were removed in 2015 when the U.S. saw the threat from Syria fading.
The U.S. has since offered to sell Turkey its Patriot missile defense systems, and an American delegation was in Ankara last week to hash out the details. Still, Turkey said, it had no intentions of giving up the S-400 purchase.
.. The basic S-400 unit has four launchers carried on a wheeled transport vehicle. It takes about eight minutes to push the 33-foot launching tubes into a vertical position, initiate tracking radar and lock onto targets.
.. The bulk of Russia’s S-400s are deployed along the country’s western border; S-400 divisions also defend the Black Sea peninsula of Crimea, which Moscow seized from Ukraine in 2014.
Several divisions are positioned on four of Russia’s Arctic territories. As polar ice gives way to global warming, both Washington and Moscow see the far north as a new frontier for Arctic sea travel, potentially connecting Asia and Europe, as well as a spot for energy exploration.
Washington accuses Moscow of violating the Cold War-era Intermediate Range Nuclear Forces Treaty, saying the Russian 9M729 missile could fly at a range prohibited by the agreement. Russia says the missile doesn’t violate the agreement.
.. Looking ahead, Almaz-Antey, the Russian arms maker that builds the antiaircraft defense systems, is designing a more advanced S-500 model to counter next-generation hypersonic and intercontinental ballistic missiles.
