Ahead of the one-year anniversary of North Korea’s outrageous sinking of the South Korean corvette Cheonan, the usual suspects, including the People’s Solidarity for Participatory Democracy (PSPD), are once again questioning whether North Korea did it. Even Democratic Party floor leader Park Jie-won — whom you’ll recall was convicted in 2003 for his role in illegally bribing North Korea with US$500 million in Hyundai’s money to agree to a summit with late Korean president Kim Dae-jung in 2000 — is getting in the act:

Lawmakers from opposition parties have demanded questions raised by the public be resolved by the government. “The South Korean people and international scholars still have doubts on why the Cheonan sank,” said Park Jie-won, floor leader of the Democratic Party. “The government should come forward actively and dissipate these doubts. He urged the government to disclose details of the Cheonan “like they did in the rescue operation in the Gulf of Aden.”

Park also demanded that meetings of the special committee for the Cheonan be restarted, as only two were held since the sinking of the corvette. “[The Democratic Party] never said that North Korea was or was not behind the sinking,” Park said. “If it was North Korea, then there should be firm measures using all methods possible so that North Korea takes proper responsibility. “President Lee Myung-bak has said that he has hard-line policies regarding North Korea, but they are not tough, and national security and inter-Korean relations have all failed,” he continued. “I feel a regional military conflict coming on as the government is in a helpless state.”

Me thinks Park would better spend his time clearing up questions as to where that US$500 million to North Korea went.

Anyway, the PSPD, which, ahem, generated controversy last year when it sent a letter questioning the South Korean government’s findings regarding the Cheonan sinking to the UN Security Council, is marking the one-year anniversary by sending letters of inquiry to the US and Swedish ambassadors to Korea. If you read Korean, you can read the inquiries here.

On an almost completely unrelated note, you’ll be happy to learn that PSPD — its views on UN action against North Korea for its brutal violations of simple human dignity not withstanding — has condemned Gaddafi’s crackdown in Libya and urged Korea to support recent measures in the UNHRC against Tripoli.
