"In response to the South Korean announcement of an impending artillery drill, North Korea telephoned the South Korean military on the morning of November 23, urging them to cancel plans to fire shells into what the North regarded as its territorial waters. The North warned that if the drill proceeded, they would respond with a "resolute physical counter-strike."

Nevertheless, the artillery drill proceeded and four hours later, North Korean artillery fired on the island. In the first round, 150 shells were shot, of which 60 hit the island. Then 20 more shells were fired in a second round. In all, four people on the island were killed and 18 wounded."

"The heads of the U.S. and South Korean Joint Chiefs of Staff agreed to change defenses against North Korean attacks yesterday, with South Korea getting a leading role in immediate retaliations and the Americans pledging support.

The agreement was made as Adm. Mike Mullen, chairman of the U.S. Joint Chiefs of Staff, made an unexpected visit to Seoul yesterday to reaffirm America’s commitment to its alliance with South Korea. Mullen spoke with his South Korean counterpart, Han Min-koo, about North Korea early yesterday.

“North Korea’s attacks are getting bolder and bolder,” said Han. “If they choose to strike again they will be punished severely, and North Korea will pay a big price.” ("U.S. top brass discusses new retaliation strategy",Korea JoongAng Daily)

"Massacre of Korean Civilians

The U.S. Army, Air Force and Navy were directly involved in the killing of about three million Koran civilians—both South Koreans and North Koreans—at many locations throughout Korea, including Masan, Sachon, Tanyang, Iksan, Changyong, Wegwan, Ducksung, Sinchun, Wonsan, Pyongyang, etc. Several hundreds of civilians refugees were blown apart when the U.S. Army blew up Wegwan and Ducksung bridges in S. Korea..... Among the several branches of the U.S. military, the U.S. Air Force was probably more responsible than any other branches for the huge number of civilian killings because of its indiscriminate shootings and bombings of civilian refugees, villages, towns, and cities in violation of Hague Conventions. At the end of the war, almost all the North Korean cities were leveled to the ground by carpet bombing, including Pyonyang, Najin, Shiniju, Wonsan, Hungnam, etc. It is reported that the U.S. dropped some 650,000 tons of bombs, including 43,000 tons of napalm bombs, during the Korean War."
