Deployment of U.S. missile defense system could reshape security in East Asia

Bloomberg, Reuters

The U.S. has opened the door to parking a ballistic missile defense system on North Korea’s doorstep, a move that could reshape North Asia’s security landscape.

Kim Jong Un’s launch Sunday of a long-range rocket prompted a reaction that his nuclear test last month did not: South Korea now says it will consider allowing the deployment on its soil of a U.S. Army system known as THAAD.

For years South Korea has danced around the idea of Terminal High Altitude Area Defense, which targets missiles in flight and could complement lower-altitude defenses already in the country. That is mainly because it risks annoying neighbor China, which has warned against THAAD being deployed on the Korean Peninsula. It could also spur Japan to look at using it.

While THAAD could be a deterrent against Kim’s regime, it would also raise the stakes for security in a region where suspicions already run high over Japan’s military aggression during World War II and a later conflict that split the Korean Peninsula between an isolated, unpredictable regime in the north and what is now a democracy in the south.

“The Chinese are doing anything possible to head off what they think might be a potential weapon that could be used against them,” said Richard Bitzinger, a senior fellow at the S. Rajaratnam School of International Studies in Singapore. “You can say everything you want, that this is not directed against the Chinese, but the fact of the matter is, it potentially could be.”

South Korea has long assured China, its biggest trading partner, it was not in talks with the U.S. about the deployment of THAAD. North Korea’s recent actions have changed that, with defense officials saying in Seoul they cannot afford to ignore calls for a stronger shield against weapons of mass destruction.

“It would draw ridicule for a sovereign nation like South Korea not to beef up its defense in the face of an increasing threat like North Korean nuclear missiles,” said Park Chang-kwon, a senior research fellow at the state-run Korea Institute for Defense Analyses in Seoul. “THAAD helps deter North Korea from seeking nuclear arms because it sends a strong message South Korea is and will keep responding with tough actions.”

South Korea opening to THAAD may increase calls in Japan to follow suit. Defense Minister Gen Nakatani said in November that Japan was considering the deployment of THAAD to counter any potential strike from North Korea. Japan and South Korea already both have Patriot missiles and the countries, alongside China and India, are among the biggest spenders on defense in Asia.

Japanese officials could not immediately be reached for comment on whether Tokyo would now seek a THAAD system after North Korea’s rocket flew over Okinawa Prefecture on Sunday.

Riki Ellison, founder of the Missile Defense Advocacy Alliance, said the launch would give Japan momentum to do so.

Some experts questioned how effective THAAD would be against the type of long-range rocket launched by North Korea and the Pentagon concedes it has yet to be tested against such a device.

John Schilling, a contributor to the Washington-based 38 North project that monitors North Korea, said THAAD’s advanced AN/TPY-2 tracking radar built by Raytheon Co. could provide an early, precise track on any such missile. But it could also carry out similar tracking of the intercontinental ballistic missiles that China counts on for strategic deterrence.

THAAD is designed to intercept and destroy ballistic missiles inside or just outside the atmosphere during their final, or terminal, phase of flight. It has so far proven effective against short- and medium-range ballistic missiles.

David Wright, co-director of the Global Security Program at the U.S.-based Union of Concerned Scientists, said that while THAAD could not shoot down the type of rocket launched Sunday its deployment could reassure the South Korean public.

“But this would mainly be symbolic,” he said. “Much of what missile defense programs are about is reassuring allies and the public with little or no capability to actually do that.”

George Lewis, a missile defense expert at Cornell University, said THAAD might provide useful information if a rocket like that launched Sunday was ever fired against U.S. territory, including Guam.

The THAAD system, built by Lockheed Martin Corp., can be transported by air, sea or land. The Pentagon has ordered two more batteries from Lockheed.

One of the four THAAD batteries based at Fort Bliss, Texas, is always ready for deployment overseas, and could be sent to Japan or South Korea within weeks, Ellison said.

In any deal with Seoul, the system would only be deployed on U.S. bases in South Korea — there are nearly 29,000 U.S. soldiers stationed — and talks on the terms for that have no clear timetable. The discussions could face resistance from a South Korean public wary of hurting ties with China.

But it would also send a message to Beijing that it should do more to rein in North Korea by using its influence. China supplies most of North Korea’s energy and food imports and the U.S. called on Beijing to curb that trade.

U.S. Secretary of State John Kerry failed last month during a visit to Beijing to secure China’s support for tougher sanctions, with the countries agreeing only to pursue a new United Nations Security Council resolution. The U.S. has sought measures such as bans on oil exports to Pyongyang.

While South Korea has sought to deepen ties with China since President Park Geun-hye took office in 2013, it has been frustrated by China’s failure to stop Kim testing nuclear devices. China warned last year that the use of THAAD would risk undermining ties, saying the Park government should reject the system in the interest of peace and stability of the whole region.

Days after what North Korea claimed was the detonation of its first hydrogen bomb, Park said publicly she would consider THAAD deployment based on national security interests. And the latest South Korean announcement deepens her change of stance. Just in September she went to Beijing to congratulate President Xi Jinping on China’s World War II victory, while U.S. President Barack Obama and Prime Minister Shinzo Abe stayed away.

“Park expended a lot of political capital in going to Beijing for the 70th anniversary military parade and has received nothing, or a slap in the face, in return,” said Ralph Cossa, president of the Pacific Forum CSIS in Honolulu. “It was naive to ever expect China to ’tilt’ toward the South, but there were hopes it would respond objectively to future North Korean provocations.”

The U.S. has played down China’s concerns about THAAD, saying the system is defensive and focused on North Korea. Still, its closer deployment to the Chinese border has the potential to exacerbate strains stemming from territorial disputes involving China in the East China Sea and South China Sea.

“It might very likely propel China to go along with its offensive missile system and put in more effort into its rather nascent missile defense program,” said Collin Koh Swee Lean, an associate research fellow at RSIS. “In the case of North Korea, in the case of China, they’ll be keen to come out with new ballistic missiles that have the ability to decoy incoming projectiles trying to intercept it and to mislead missile defenses so as to have a higher chance of hitting the target.”

    China just announced that they regret North Korea’s new missile launch? Why are they now pretending to be concerned, since they’ve been providing materials and preventing strong sanctions against North Korea for past 15 years?
