It seems to me that it is pretty clear that the ROK wants THAAD in Korea, but the trick for them is figuring out how to deploy it without pissing off the Chinese:
With growing controversy in Northeast Asia surrounding U.S. ambitions to deploy an advanced antiballistic missile defense system on the Korean Peninsula, the Pentagon has reversed its earlier position that Seoul and Washington were discussing the issue.
In the latest media briefing, the Pentagon’s press secretary made clear the United States and South Korea are not having official discussions on possible deployment of the Terminal High-Altitude Area Defense system, better known as Thaad.
“There are no formal consultations or discussions about Thaad with our Republic of Korea counterparts, no formal consultations about Thaad. And we want to be very clear about that,” said Navy Rear Admiral John Kirby on Friday in Washington. “We do discuss a full range of military capabilities with our allies in South Korea, of course, and some of those do include missile defense. But there are no consultations with respect to Thaad.”
Kirby said it is for the South Korean government and its people to decide what is of strategic value to their country.
The Pentagon’s verification came as Seoul, Washington, Beijing and Moscow have been engaged in an intensifying diplomatic tug-of-war in recent weeks over possible Thaad deployment. Throughout this month, defense officials in Beijing and Washington took turns nudging Seoul to make up its mind.
Thaad is a U.S. defense system designed to shoot down missiles using a hit-to-kill approach. Because it is equipped with a radar system that can cover more than 1,000 kilometers (621 miles), deployment of a Thaad battery in Korea has been a sensitive issue. Both China and Russia see it as a threat to their security interests that could be used for surveillance.
Beijing and Moscow appeared to be particularly sensitive to the Thaad system because of the AN/TPY-2 – a high-resolution, rapidly deployable X-Band radar designed to detect, track and identify ballistic missiles at long distances and very high altitudes.
During a press conference Feb. 10, Kirby said South Korea and the United States were discussing possible deployment of Thaad.
“I think we all recognize the importance of the capability,” Kirby said about the Thaad system in Washington. “There are constant discussions, and certainly with our South Korean allies about that.”
While offering no details, Kirby said, “It’s an important capability. It’s one that we talk to them about. That’s really as far as I can go today.”
Another U.S. government official, Lt. Col. Jeff Pool, a Pentagon press officer, supported Kirby’s earlier comments, saying officials in Washington and Seoul often talked informally about Thaad, although there never was an official discussion.
“It would be untruthful to say we haven’t informally discussed [it] because we already had a site survey in the ROK [South Korea] and Gen. [Curtis] Scaparrotti said he wanted it,” Pool told Korean correspondents in Washington, referring to earlier statements by senior U.S. defense officials. [Joong Ang Ilbo]
