According to the memorandum, the nuclear issue on the Korean Peninsula is attributable to the nuclear threat directly posed to the DPRK by the U.S. which resorted to the war of aggression and hostile policy toward the DPRK.

The document goes on:

The U.S. imperialists, which provoked the war for aggression of Korea in June 1950, shipped nuclear weapons to south Korea in August that year and at the end of the year openly disclosed its plan to drop 30-50 A-bombs in Korea-China border areas.

Eisenhower, U.S. president-elect at that time, blustered on May 13, 1953 that it will be more beneficial to use an atomic bomb rather than conventional weapons in Korea when taking into account the financial aspect.

After it sustained a shameful defeat in the Korean war, the U.S. has viciously resorted to nuclear threats to the DPRK, pursuant to its moves for a new war.

The U.S. set out for nuclear weaponization of its forces present in south Korea. It reorganized its forces' division into Pentomic A-bomb Division equipped with tactical nuclear weapons and introduced Honest John nuclear missile battalion and 280 mm atomic artillery pieces battalion.

In 1958 the U.S. brought 588 tactical guided missile battalion of the U.S. air force and set up the 4th guided missile command of the U.S. forces.

Entering the 1960s, the U.S. renamed Pentomic A-bomb Division ROAD Division and introduced to south Korea atomic and guided weapons with various missions.

After the Vietnamese war in the mid-1970s, the U.S. declared south Korea as an area for defending front and pressed for the policy for turning south Korea into a nuclear base.

Member of the U.S. House of Representatives Ronald, speaking at a parliament, confessed that the U.S. shipped more than 1 000 nuclear weapons to south Korea and deployed 54 airplanes for carrying nuclear bombs.

In the 1980s the U.S. spurred the modernization of the nuclear hardware of its forces in south Korea.

Early in the 1980s the U.S. deployed 31 155mm nuclear shells, 133 nuclear bombs for air use, 63 nuclear shells for 8 inch howitzers and 21 nuclear land mines before any other base of its forces overseas.

South Korea turned into the world's biggest nuclear outpost with the stockpile of nuclear weapons such as bombs, shells, warheads, land mines and carrier means as well as nuclear bases and arsenals.

The U.S. nuclear threats were vividly manifested in its open declaration to use nuclear weapons in Korea.

In January 1968 when the U.S. imperialists' armed spyship "Pueblo" was captured, the U.S. reviewed the nuclear attack plan. When the spy plane EC-121 was brought down from the sky above Korea in April 1969, the U.S. put tactical bombers mounted with nuclear weapons on standby and the then U.S President Nixon said that he approved the use of A-bomb in case Korea makes counterattack.

When the Korean Peninsula was almost in the state of "emergency" in 2002, the U.S. made the preemptive nuclear attack on the DPRK a fait accompli by granting the U.S. forces' first use of nuclear weapons. It even asserted that it will develop smaller nuclear weapons for destroying underground facilities.

The present Obama administration has steadily increased nuclear threats, putting the DPRK in the list of preemptive nuclear attack targets.

The U.S. at the 41st annual security consultative meeting in 2009 with the south Korean puppet forces made public a joint press release in which it promised the offer to south Korea of the nuclear umbrella, capacity for striking with conventional weapons, a missile shield and other extended deterrence.

The U.S. forces and the south Korean forces worked out a number of scenarios for invading the DPRK and pushed forward the moves to put big and annual joint military drills including Key Resolve, Foal Eagle and Ulji Freedom Guardian into an actual war every year.

The memorandum disclosed the south Korean puppet forces as a chieftain that increased the danger of a nuclear war on the Korean Peninsula and hampered the solution to the nuclear issue in league with the U.S.

The successive puppet regimes of south Korea connived at and encouraged the U.S. shipment of nuclear weapons to south Korea and actively joined the U.S. in its moves for a nuclear war against the DPRK.

In the 1980s, traitor Chun Doo Hwan in alignment with the U.S. brought to south Korea a neutron bomb called the "weapon of evil in the 20th century".

The puppet forces fully entrusted the U.S. with the right to use the nuclear weapons deployed in south Korea.

They formed the extended deterrence policy committee with the U.S. and agreed to hold exercises for using the extended deterrence means. Since 2011 they have put them into practice.

They have pushed forward the development of nuclear weapons in secrecy while taking an active part in the U.S. moves for a nuclear war.

The Park Chung Hee military dictatorial regime, in particular, laid out a nuclear weapons development plan and mulled processing nuclear fuel in 1969. It formed a nuclear and missile development team in 1974 and arranged nuclear fuel development area in 1976.

In September 1978, it test-fired ground to ground missile Paekgom capable of mounting nuclear warheads developed by the defense scientific research institute.

In November 1985, it completed the construction of a facility for extracting plutonium and put it into full operation from 1987.

South Korea directed efforts into the development of nuclear weapons delivery means as evidenced by the development of 256km range ground to ground missile Hyonmu capable of carrying out nuclear warheads and their deployment for an actual war in 1987.

It is openly calling for "nuclear weaponization" now.

It has viciously obstructed the negotiations for the denuclearization of the Korean Peninsula.

Traitor Kim Young Sam resorted to the whole gamut of machinations to break down the DPRK-U.S. negotiations by currying favor with the U.S.

The cursed traitor Lee Myung Bak group threw hurdles in the way of the DPRK-U.S. talks, claiming that the "nuclear issue of the north" is destroying the peace and stability on the Korean Peninsula and obstructing the efforts for the development of the south-north relations.

The Lee Myung Bak group called the DPRK's peaceful satellite launch "a long-range missile launch" till the last moments of its office and worked with bloodshot eyes to materialize international "sanctions" citing the launch as a pretext.

The memorandum said that the DPRK's access to nuclear deterrence for self-defence was entirely attributable to the U.S. and its stooge south Korean puppet forces.

The DPRK has constantly called for the withdrawal of the U.S. nuclear weapons since their shipment to south Korea and always maintained that the Korean Peninsula be denuclearized while working hard for the solution to the nuclear issue.

Far from responding to the DPRK's sincere efforts, the U.S. prodded some circles of the International Atomic Energy Agency to create sort of "discrepancy" of nuclear materials and forced the DPRK to receive special inspection. It also resumed Team Spirit joint military exercises and openly increased the danger of a nuclear war.

The DPRK has made sincere efforts for the settlement of the nuclear issue on the peninsula through direct talk with the U.S. directly responsible for the issue.

The DPRK's efforts for the peaceful settlement of the nuclear issue through dialogue have faced a serious challenge as junior Bush administration took power in the U.S.

The U.S. hostile policy toward the DPRK has remained unchanged under the present Obama government.

The Obama administration kicked up anti-DPRK nuclear racket, calling the DPRK's peaceful satellite launch that was recognized by international law "a long-range missile launch". This made the nuclear issue on the Korean Peninsula more serious one.

The situation eloquently proves that the DPRK was just when it decided to access nuclear deterrence for self-defence to cope with the U.S. nuclear threats.

The memorandum warned that the U.S. and the south Korean puppet forces should know that they will get nothing but destruction and disaster for their provocative anti-DPRK nuclear racket.
