Early on morning of October 11, North Korean hackers were able to hack into the South Korean government computers and stole about 235 GB of data. The stolen data included 300-lower classified, confidential documents, and there were also classified wartime plans drawn up by the U.S. and South Korea.

Mr. Rhee Cheol-hee, a South Korean lawmaker, had stated to reporters that one of the documents that was stolen included South Korea’s military plan of removing North Korea leader, Kim Jong-Un, if war between the Korean Peninsula breaks out. The hackers had used a computer vaccine service, and South Korea had been able to trace the IP address, of the vaccine, which originated in Shenyang, China.

In 2010, the U.S. broke into North Korea’s computer system; targeting Reconnaissance General Bureau, which is North Korea’s equivalent of the US C.I.A. Last month, U.S. strategic bombers, and fighters jets, flew along the East Coast of North Korea. North Korea claimed a right to shoot any American warplanes flying near the country.

The Pentagon hasn’t yet released a statement, but spokesperson, Army Col. Rob Manning, stated that “I can assure you we are confident in our security in our operations plans and our ability to deal with any threat from North Korea.” He also added, “The operations plan that they are referring to is a bilateral plan, so the Republic of Korea-U.S. alliance remains steadfast in their commitment to make sure they safeguard that information and ensure readiness on Korean Peninsula to counter any North Korean threats.”

Trump tweeted on Monday, October 9th, “Our country had been unsuccessfully dealing with North Korea for 25 years, giving billions of dollars and getting nothing. Policy didn’t work.” He then tweeted later in the afternoon “Presidents and their administrations had been talking to North Korea for 25 years, agreements been made and massive amounts of money had been paid…hasn’t worked, agreements violated before the ink was dry, making fools of US negotiators. Sorry but only one thing will work!” When the reporters asked Trump what he meant by his tweets his only response was “You’ll figure it out pretty soon.”
