2013 Korean crisis

The 2013 Korean crisis, also referred to as the North Korean crisis by media, was an escalation of tensions between North Korea and South Korea, the United States, and Japan that began because of United Nations Security Council Resolution 2087, which condemned North Korea for the launch of Kwangmyŏngsŏng-3 Unit 2. The crisis was marked by extreme escalation of rhetoric by the new North Korean administration under Kim Jong-un and actions suggesting imminent nuclear attacks against South Korea, Japan, and the United States.

Early background
In 1957, the United States withdrew from the article 13(d) in the Korean Armistice Agreement, which prohibited the foreign signatories from sending additional equipment to Korea. The US subsequently sent nuclear weapons to Korea in January 1958, such as MGR-1 Honest John. This led North Korea to forward deploy their troops to the border, so if hit with a nuclear weapon, it would also affect their counterparts, South Korea and United States. North Korea also requested help as early as 1963 with developing its own nuclear weapons to counter the perceived threat of nuclear war in Korea.

In 1994, Following North Korea's threat to withdraw from the Nuclear Non-Proliferation Treaty, United States and North Korea entered into an Agreed Framework. In 2003, North Korea chose to withdraw from the Nuclear Non-Proliferation Treaty. Since then it has been subject to a series of sanctions by the UN Security Council concerning its nuclear program. These sanctions include: Resolution 1695, Resolution 1718, Resolution 1874, and Resolution 2087.

Satellite launch
In April 2012, Kim Jong-un formally took over as leader of the North Korean ruling party leadership. On 13 April 2012, North Korea attempted and failed to launch an artificial satellite called Kwangmyŏngsŏng-3, which was planned to mark the centenary of the birth of Kim Il-sung, the founder of the DPRK. The launch was widely seen as a long-range missile test, of the sort that North Korea had agreed to suspend in return for US food aid. North Korea has said it was no longer bound by the agreement, which also banned nuclear tests.

In October 2012, days after South Korea and the US unveiled a new missile deal, North Korea reported it had missiles that were capable of reaching the US mainland. On December 12, 2012, North Korea launched a new artificial satellite called Kwangmyŏngsŏng-3 Unit 2 into space.

Most of the nations of the world condemned the action, including China, which by a military pact is required to defend North Korea in the event of aggression. In addition, historical rivals the United States, Japan and South Korea claimed that it was a military trial for war, with the sole mission of provoking political opponents.However, North Korean government said the launch was solely to put a satellite into orbit, denying that it was a military trial.

On January 22, 2013, United Nations Security Council condemned the satellite launch, regarding this as a violation of a ban on North Korean ballistic missile tests, as the rocket technology is the same. Strengthening the sanctions included in previous Resolutions 1718 (2006) and 1874 (2009).

North Korea denounced sanctions UNSC imposed under UNSC Resolution 2087. on the January 23 the government of North Korea announced the continuation of their tests not only devoted to missiles, but clearly with an effort to facilitate nuclear weapons purposes. Moreover, North Korea directly threatened the U.S., announcing that they could launch long-range missiles against that country.

"We do not hide that we will launch a series of satellites and long-range rockets and carry out nuclear tests in the next higher level new phase of the struggle against the United States, the sworn enemy of the Korean people."

- National Defense Commission of North Korea

The North Korean government accused the United States at the United Nations of leading a "unprecedented movement against North" with new sanctions and impeding Pyongyang's efforts to develop its economy. State television also said that "this has proven once again that the North must defend its sovereignty by itself. It has become clear that there can be no demilitarization of the Korean peninsula before the world has denuclearized".

January 22

 * U.N. Security Council Resolution 2087, condemning the North Korean satellite launch as a violation of a ban on North Korean ballistic missile tests, as the rocket technology is the same, is unanimously adopted. The agreement broadened the sanctions included in previous resolutions.

January 24

 * North Korea announced its plans to carry out a new nuclear test and more long-range rocket launches, all of which it said are a part of a new phase of confrontation with the United States. The statement called the United States the "sworn enemy of the Korean people".

February 12

 * North Korea conducted a nuclear weapon test. The test was widely condemned internationally. The Secretary-General of the United Nations, Ban Ki-moon, condemned the test, and called it a "clear and grave violation" of Security Council resolutions.

February 15

 * North Korea informed China that it would conduct one or two further nuclear tests in 2013.

March 7

 * During Foal Eagle, annual training exercise conducted between South Korea and the United States, North Korea threatened to abandon the Korean Armistice Agreement, arguing the exercises threatened North Korea with nuclear weapons and that the U.S. was unwilling to negotiate a peace treaty to replace the armistice. JoongAng Ilbo reported that American vessels equipped with nuclear weapons were participating in the exercise. The U.S. Department of Defense publicly announced that U.S. Air Force B-52 bombers from Andersen Air Force Base in Guam flown over South Korea were reaffirming the U.S.'s "nuclear umbrella" for South Korea.

March 8

 * The North Korean government announced that it was withdrawing from all non-aggression pacts with South Korea in response to United Nations Security Council Resolution 2094, which condemned its recent nuclear test.  The announcement said it was closing its joint border crossing with South Korea and cutting off the hotline to the South.

March 13

 * North Korea confirmed it ended the 1953 Korean Armistice Agreement, declaring that North Korea "is not restrained by the North-South declaration on non-aggression" and warned that the next step was an act of "merciless" military retaliation against its enemies.

March 15

 * United States Secretary of Defense Chuck Hagel announced that the U.S. will add 14 more Ground-Based Interceptor (GBI) missiles, one of the key components of the Ground-based Midcourse (GMD) ballistic missile defense system, at Fort Greely, Alaska, boosting the total number of GBI missiles from 30 back to the 44 planned by the Bush administration. Currently, 30 GBI missiles are based at two sites in the U.S., four at Vandenberg Air Force Base in California, and 26 at Fort Greely in Alaska. The U.S.'s GMD program uses land-based missiles to intercept incoming ballistic missiles in the midcourse phase of their flight, outside the earth atmosphere. GMD is designed to defend against intercontinental ballistic missiles (ICBMs). In contrast, the well-known land-based Patriot system with Patriot PAC-3 missiles or the new land-based Terminal High Altitude Area Defense (THAAD) system (as well as the sea-based Aegis Ballistic Missile Defense system) is designed to defend against theatre ballistic missiles (TBMs) including short-range (SRBM), medium-range (MRBM), and intermediate-range (IRBM) missiles. Admiral James A. Winnefeld, Jr., Vice Chairman of the Joint Chiefs of Staff also expressed his concern over the threat of North Korea's KN-08 ICBMs, telling reporters at the Pentagon on March 15 that this ICBM has emerged as a threat "a little bit faster than we expected." KN-08 missiles were first displayed on 16-wheel carrier trucks during a 2012 military parade, but there are doubts about their authenticity.   In addition, Secretary Hagel said that the U.S. is planning to deploy an additional AN/TPY-2 radar, a part of GMD ballistic missile defense system in Japan. This second radar will provide improved early warning and tracking of any missile launched from North Korea at the U.S. or Japan. A first land-based AN/TPY-2 radar was positioned in northern Japan and has been operational since 2006, a second installation is scheduled to be emplaced in central Japan soon, but it is not likely to be fully functional for several more months to come.

March 16

 * U.S. Secretary of Defense Chuck Hagel announced that Fort Greely in Alaska might have to be expanded to protect the United States from potential threats from Iran and North Korea.

March 20

 * There was a cyber-attack against South Korea which added to tensions. It was later confirmed by the South Korean government that North Korea was behind the attack.

March 26

 * The U.S. again dispatched B-52 bombers from Guam to overfly South Korean territory as part of the ongoing Foal Eagle exercise. These flights were, according to US Department of Defense sources, routine flights intended to demonstrate America’s capability of maintaining a "continuous bomber presence" in the region.
 * Japan was to deploy three Japanese Maritime Self-Defense Force (JMSDF) destroyers equipped with Aegis Ballistic Missile Defense system (Aegis BMD) according to Japanese media. Citing unnamed government officials, Japanese news reports said 2 of the destroyers would depart from Sasebo Naval Base in Nagasaki Prefecture, and head for the East China Sea. One of these ships from Sasebo was confirmed as the JDS Chokai (DDG-176). A third destroyer would deploy from Maizuru, Kyoto Prefecture, and head for the Sea of Japan. These warships could either be Kongo class or Atago class guided-missiles destroyers or both. All three ships are equipped with the RIM-161 Standard Missile 3 (SM-3) Block IA, a missile co-developed by and purchased from the U.S., according to Lt. Choji Yoshida, spokesman for the JMSDF Sasebo district headquarters. Japan also moved Patriot PAC-3 missile batteries to Okinawa to intercept a North Korean missile should any piece of it approach Japanese territory or waters.

March 27

 * Confirmation of the severing of the hotline between the North and the South—the last remaining communication link between the two countries at that time—was publicly announced, the same date that the hotline was cut off. According to the Korean Central News Agency, a senior North Korean military official stated: "Under the situation where a war may break out any moment, there is no need to keep up North-South military communications" prior to the cessation of the communication channel.

March 28

 * Two U.S. Air Force B-2A Spirit stealth bombers flew roundtrip from Whiteman Air Force Base in Missouri to the skies over the Korean Peninsula where they unloaded inert munitions on a South Korean bombing range. Flying nonstop with the assistance of in-flight refuelers, Pentagon officials called this mission a clear demonstration of "the United States’ ability to conduct long range, precision strikes quickly and at will". A flight of seven B-1B Lancer bombers was also deployed to Andersen Air Force Base in Guam.

March 30

 * North Korea declared a 'state of war' against South Korea. A North Korean statement promised "stern physical actions" against "any provocative act". North Korean leader Kim Jong-un declared that rockets were ready to be fired at American bases in the Pacific. This was in response to two nuclear-capable American B-2 stealth bombers flying over the Korean peninsula on March 28. The day before North Korea's declaration, the United States Department of Defense said, "The United States is fully capable of defending itself and our allies against a North Korean attack. We are firmly committed to the defense of South Korea and Japan."

March 31

 * Two U.S. Air Force F-22A Raptor stealth fighters were deployed to Osan Air Base, the main U.S. Air Force base in South Korea, from Kadena Air Base in Okinawa, Japan. The aircraft are on static display at Osan Air Base as part of the Foal Eagle exercise to provide bilateral training for the US and the Republic of Korea military and to provide South Korean senior leaders with an orientation to the aircraft, which are an advanced capability available for the defense of South Korea," Pentagon spokesman George Little said on April 1.

April 2

 * North Korea said it would restart a nuclear reactor capable of producing plutonium at the Yongbyon Nuclear Scientific Research Center, which was closed after six-party talks in 2007.
 * The IT webzine BGR carried an article stating that the hacker group Anonymous had started Operation North Korea, calling for ‘controversial leader Kim Jong-un [to] resign’, ‘install free democracy’ ‘abandon its nuclear ambitions’, ‘uncensored Internet access’, etc. The hackers also proclaimed that if the North Korean government does not accede to their demand, they will wage “Cyber War.”

April 3

 * North Korea closed entry to the Kaesong Industrial Region to South Koreans. The South Koreans already there were allowed to leave (most stayed voluntarily to continue working). The Kaesong Industrial Region remaining open had previously been seen as a sign that the crisis was not as serious as the rhetoric suggested. The New York Times reported following the closure that "The fate of Kaesong is seen as a crucial test of how far North Korea is willing to take its recent threats against the South. Its continued operation was often seen as a sign that Pyongyang’s verbal militancy was not necessarily matched by its actions." Kaesong was briefly closed three times in 2009.
 * The Pentagon ordered a U.S. Army Terminal High Altitude Area Defense (THAAD) advanced ballistic missile defense battery to be deployed to Guam within the next few weeks. The THAAD missile is designed to intercept the Theatre Ballistic Missile (TBM), and consists of a SRBM, a MRBM, and an IRBM. It intercepts missiles during the descent phase at an altitude higher than the current U.S. Army shorter range Patriot missile, that can intercept a TBM only during the terminal (final) phase of flight. U.S. Navy Arleigh Burke class guided-missiles destroyer USS Decatur (DDG-73) equipped with the Aegis Ballistic Missile Defense system (Aegis BMD) also was sent to the Western Pacific near the Korean Peninsula, to join another destroyer, the USS John S. McCain (DDG-56), to perform a ballistic missile defense mission in response to growing threats. A third warship, the USS Fitzgerald (DDG-62), is also available. These ships are capable of carrying RIM-161 Standard Missile 3 (SM-3) Block IA Anti-Ballistic Missiles (ABMs). The latest generation of Standard missile, the RIM-174 Standard Missile 6 (SM-6) or Standard Extended Range Active Missile (Standard ERAM), with its advanced active radar seeker, can also be deployed on these warships. SM-6 is capable of defending against a TBM in their terminal phase of flight at an altitude up to 33 km (110,000 ft) and is now superseding RIM-156 Standard Missile 2 Extended Range (SM-2ER) Block IV as U.S. Navy terminal phase TBM interceptor. The Navy received the SM-6 into service in February 2013. U.S. Department of Defense spokesman George Little denied reports that a Sea-Based X-band radar (SBX radar), a floating radar used to track an adversary's missiles as part of a Ground-based Midcourse Defense (GMD) ballistic missile defense system, was being deployed to the waters off Japan, saying no decisions had been made about what would be done with the radar once at-sea testing in the region was finished.
 * The North Korean military said it had "ratified" a merciless attack against the United States, potentially involving a "cutting-edge" nuclear strike, and that war could break out "today or tomorrow".
 * The hacker group Anonymous claimed it had stolen 15,000 user passwords from Uriminzokkiri.com website, as part of a cyberwar against the DPRK.

April 4

 * North Korea moved what is believed to be a BM25 Musudan mobile intermediate-range ballistic missile (IRBM) to its east coast, possibly in preparation for a drill or test-firing. Many nations, specifically Japan, South Korea, and the United States, viewed this move as a continuation of North Korea's attempts to provoke confrontation throughout the beginning of 2013.
 * Anonymous claimed to have hacked into the Uriminzokkiri main website, and the Twitter and Flickr pages representing the website.

April 5

 * Multiple countries, including the United Kingdom, Russia, and Sweden (who provides limited consular services for the United States in North Korea ), were warned that they should evacuate their embassies by April 10. The UK embassy stated they had no plans to do so.
 * South Korea has dispatched two Sejong the Great class guided-missile destroyers equipped with Aegis combat system to watch both sides of the peninsula for a possible North Korean missile launch Yonhap news agency reported, citing Republic of Korea (ROK) Navy official sources. These ships are outfitted with the powerful AN/SPY-1D radar capable of detecting ballistic missiles and accurately tracking their trajectories as soon as North Korea launches them. However they cannot yet intercept the incoming ballistic missiles using their primary air defense weapon consisting of 80 RIM-66 Standard Missile 2 Medium Range (SM-2MR) Block IIIA and IIIB missiles. There are no confirmed reports that South Korea had bought RIM-156 Standard Missile 2 Extended Range (SM-2ER) Block IV missile, the newer version of Standard missile capable of intercepting ballistic missiles during their terminal phase of flight. SM-2ER Block IV has been deployed on U.S. Navy guided-missiles cruisers and destroyers equipped with Aegis combat system for many years. With North Korea prepared for launching missiles and South Korea placing naval destroyers on its coasts, tensions in the Korean peninsula remain at a heightened state. Anticipating the upcoming North Korea's missile test the U.S. set to deploy a RQ-4 Global Hawk Unmanned Aerial Vehicle (UAV) surveillance aircraft to Japan to boost surveillance capabilities over North Korea. The Global Hawk will be stationed at Misawa Air Base in northern Japan. The U.S. military informed Japan last month about plans to deploy the plane between June and September but may bring the date forward, it said, following reports about North Korea’s preparations for missile launches.
 * Due to Kim Jong-un's rhetoric, South Korea's stocks dropped by 1.6% according to the KOSPI index.

April 6

 * The Foreign Ministry of Germany stated that their embassy in Pyongyang will continue working, but it will be evaluated regularly for security and exposure. The United Kingdom reassured that they are staying and Sweden and France have also stated that they have no plans for evacuation. However Russia is considering the evacuation of staff due to the tensions.

April 7

 * The Pentagon announced that the Minuteman III missile test at Vandenberg Air Force Base, which was planned for April 9, would be postponed. The test was not associated with the North Korea crisis, but the United States decided to hold off "given recent tensions on the Korean Peninsula," said a Department of Defense official.

April 8

 * North Korea planned to withdraw all of its workers from the Kaesŏng Industrial Region.
 * South Korea suspected that North Korea was preparing for a fourth nuclear test in Punggye-ri.
 * Japan’s Defense Minister Itsunori Onodera has ordered its military to shoot down any North Korean missile headed towards its territory, which will see these destroyers deployed in the Sea of Japan. Suga also told a news conference that Japan would use those anti-ballistic missile systems only to defend Japanese territory. Prime Minister Shinzo Abe has proposed that the government change its interpretation of the Constitution so Japan can intercept a missile fired at the U.S., but an advisory panel to Abe is still discussing relevant issues and the government has maintained its current interpretation. Shooting down a missile aimed at the U.S. would fall within the category of collective self-defense as defined by the United Nations Charter. The government interprets the war-renouncing Constitution as prohibiting the exercise of the right of collective defense.
 * Using the hacked Uriminzokkiri Twitter account, Anonymous announced that the second round of Operation North Korea will occur soon.

They have been deployed apparently to defend the ministry’s headquarters and key JSDF units as well as the heart of the capital, given the limited range of the missile, which is about 30 km. PAC-3 missiles are designed to intercept ballistic missiles that evaded the defense layer established by already deployed Aegis BMD system equipped guided-missiles destroyers. Officials from Seoul revealed that North Korea was likely planning to launch missiles on or after April 10, a date which had already been warned about.

The Kaesong Industrial Complex, the last symbol of inter-Korean relations, is technically shut down for the moment amid high tensions in the Korean Peninsula. North Korea states that South Korea is fully culpable for the shutting down of the Kaesong Complex, and claims that any finished products left at the Kaesong Complex will belong to the North. Experts are unclear as to what the future lies ahead of the Kaesong Complex and when it might reopen again. Meanwhile, South Korea delayed the decision about whether to continually give support of electricity to Kaesong or not. Company leaders at Kaesong fear their company's fate and are worrying about the conditions of the machines in the factory.

Continued tensions
On October 8, 2013, North Korea prepared its army and warned the United States of a "horrible disaster". A few days later, North Korea refused to sign a non-aggression pact with the United States as it warned of "retaliatory strikes" and "an all-out war of justice". It urged the United States to stop their military drills, which was described as "nuclear blackmail". Experts subsequently reported that North Korea poised short-ranges missiles for a test off its east coast. On 21 October, North Korea warned South Korea of "merciless firing" if it continued to develop non-explosive shells that contain anti-Pyongyang leaflets.

On November 12, 2013, senior North Korean official Kim Tae-gil threatened the United States, South Korea and Japan with a "nuclear catastrophe".
