U.S. President Donald Trump's suggestion that South Korea will have to foot the $1.1 billion bill for the Terminal High Altitude Area Defense (THAAD) system being placed in its territory amounts to only a minor addition to the long list of controversies spurred by the deployment. The president's comments sparked a flurry of conversations over the weekend between South Korean and U.S. officials, who downplayed the statement. And in the short term, the results of South Korea's presidential election and the objections China has raised about the THAAD's effect on its own security will have a greater impact on the long-term prospects of the U.S. missile defense system intended to counter North Korea's thriving ballistic missile program.
With the blessing of South Korea's interim government, the U.S. military is hurrying to position and test the THAAD system before voters head to the polls May 9 to select ousted President Park Geun Hye's replacement. After all, the candidate for the progressive Democratic Party and the race's current front-runner, Moon Jae-in, has said he would revisit Seoul's agreement to host the THAAD if he wins the presidency. An operational test of the system, which is being set up on land supplied by Seoul, is expected later this week.
