The signed armistice established a “complete cessation of all hostilities in Korea by all armed force”
[2] that was to be enforced by the commanders of both sides. Essentially a complete cease-fire was put into force. The armistice is however only a cease-fire between military forces, rather than an agreement between governments.
[28] No
peace treaty was signed which means that the Korean War has not officially ended....
In September 1956 the U.S.
Chairman of the Joint Chiefs of Staff Admiral Radford indicated that the U.S. military intention was to introduce atomic weapons into Korea, which was agreed to by the
U.S. National Security Council and
President Eisenhower.
[32] However paragraph 13(d) prevented the introduction of nuclear weapons and missiles.
[33] The U.S. unilaterally abrogated paragraph 13(d), breaking the Armistice Agreement, despite concerns by United Nations allies.
[34][35][36] At a meeting of the
Military Armistice Commission on June 21, 1957, the U.S. informed the North Korean representatives that the United Nations Command no longer considered itself bound by paragraph 13(d) of the armistice.
[37][38] In January 1958 nuclear armed
Honest John missiles and
280mm atomic cannons were deployed to South Korea,
[39]followed within a year by
atomic demolition munitions[40] and nuclear armed
Matador cruise missiles with the range to reach China and the Soviet Union.
[35][41]
The U.S. believed that North Korea had introduced new weapons contrary to 13(d), but did not make specific allegations.
[42] North Korea also believed the U.S. had introduced new weapons earlier, citing
Neutral Nations Supervisory Commission inspection team reports for August 1953 to April 1954....
North Korea has announced that it will no longer abide by the armistice at least 6 times, in the years 1994, 1996, 2003, 2006, 2009, and 2013.
[47][48]
On April 28, 1994, North Korea announced that it would cease participating in the
Military Armistice Commission, but would continue contact at
Panmunjom through liaison officers and maintain the general conditions of the armistice. North Korea stated it regarded the U.S. deployment of
Patriot missiles in South Korea as terminating the armistice.
[49][50]
In January 2002 U.S. President
George W. Bush labeled North Korea in his first
State of the Union Address as part of an
Axis of Evil.
[51] In October 2006 North Korea conducted
its first nuclear weapons test. On May 27, 2009, North Korea announced it no longer felt bound by the armistice agreement.
[52] There were two isolated violent incidents in 2010, the
ROKS Cheonan sinking (attributed to North Korea, despite denials) and the North Korean
Bombardment of Yeonpyeong.
In 2010, the U.S. position regarding a peace treaty was that this can only be negotiated when North Korea "takes irreversible steps toward denuclearization".
[53]
In 2013 North Korea argued the armistice was meant to be a transitional measure. It argued that North Korea had made a number of proposals for replacing the armistice with a
peace treaty, but the U.S. had not responded in a serious way. It further argued the
Military Armistice Commission and
Neutral Nations Supervisory Commission had long been effectively dismantled, paralysing the supervisory functions of the armistice. North Korea believes the annual U.S. and South Korean exercises
Key Resolve and
Foal Eagle are provocative and threaten North Korea with nuclear weapons.
[54] JoongAng Ilbo reported the U.S. vessels equipped with nuclear weapons were participating in the exercise,
[55] and
The Pentagon publicly announced that
B-52 bombers flown over South Korea were reaffirming the U.S. "nuclear umbrella" for South Korea.
[56]
In March 2013, North Korea announced that it was scrapping all non-aggression pacts with South Korea, along with other escalations such as closing the border and closing the
direct phone line between the two Koreas.
[57] North Korea stated it had the right to make a preemptive nuclear attack.
[57] A United Nations spokesman stated the armistice agreement had been adopted by the U.N. General Assembly, and could not be unilaterally dissolved by either North Korea or South Korea.
[58] On March 28, 2013, the U.S. sent two
B-2 Spirit stealth bombers to
South Korea to participate in ongoing military exercises in the region, including the dropping of inert munitions on a South Korean bomb range. This was the first B-2 non stop, round-trip mission to Korea from the United States.
[59] Following this mission, North Korean state media announced that it was readying rockets to be on standby to attack U.S. targets.
[60] In May 2013, North Korea offered to enter into negotiations for a peace treaty to replace the armistice agreement.
[61][62][63]
In August 2016, North Korea installed anti-personnel mines to prevent potential defectors of its front-line border guards around the "Bridge of No Return,” situated in the Joint Security Area (JSA).
[64] The UN Command has protested this move as it violates the Armistice agreement which specifically prohibits armed guards and anti-personnel mines.
[64]
In 2016, when North Korea proposed formal peace talks, the U.S. adjusted its position from a pre-condition that North Korea had taken "irreversible steps toward denuclearization", to the negotiations including curbing the nuclear program. The discussions did not take place. State Department spokesman said "[North Korea] periodically raise the idea and it never really gets far".
The Armistice stopped the killing but it is only honored defacto and has been repeatedly violated by both sides.
