DateMinutes to midnightReason given by Bulletin of Atomic Scientists
2
01/06/19477As the Bulletin evolves from a newsletter into a magazine, the Clock appears on the cover for the first time. It symbolizes the urgency of the nuclear dangers
3
01/10/19493The Soviet Union denies it, but in the fall, President Harry Truman tells the American public that the Soviets tested their first nuclear device, officially starting the arms race.
4
01/09/19532After much debate, the United States decides to pursue the hydrogen bomb, a weapon far more powerful than any atomic bomb.
5
01/01/19607Political actions belie the tough talk of "massive retaliation." For the first time, the United States and Soviet Union appear eager to avoid direct confrontation
6
01/10/196312After a decade of almost non-stop nuclear tests, the United States and Soviet Union sign the Partial Test Ban Treaty, which ends all atmospheric nuclear testing.
7
01/01/19687Regional wars rage. U.S. involvement in Vietnam intensifies, India and Pakistan battle in 1965, and Israel and its Arab neighbors renew hostilities in 1967. Worse yet, France and China develop nuclear weapons to assert themselves as global players.
8
01/04/196910Nearly all of the world's nations come together to sign the Nuclear Non-Proliferation Treaty. The deal is simple--the nuclear weapon states vow to help the treaty's non-nuclear weapon signatories develop nuclear power if they promise to forego producing nuclear weapons.
9
01/06/197212The United States and Soviet Union attempt to curb the race for nuclear superiority by signing the Strategic Arms Limitation Treaty (SALT) and the Anti-Ballistic Missile (ABM) Treaty.
10
01/01/19749South Asia gets the Bomb, as India tests its first nuclear device. And any gains in previous arms control agreements seem like a mirage.
11
01/01/19807Thirty-five years after the start of the nuclear age and after some promising disarmament gains, the United States and the Soviet Union still view nuclear weapons as an integral component of their national security.
12
01/01/19814The Soviet invasion of Afghanistan hardens the U.S. nuclear posture. Before he leaves office, President Jimmy Carter pulls the United States from the Olympics Games in Moscow and considers ways in which the United States could win a nuclear war.
13
01/01/19843U.S.-Soviet relations reach their iciest point in decades. "Every channel of communications has been constricted or shut down; every form of contact has been attenuated or cut off.
14
01/01/19886The United States and Soviet Union sign the historic Intermediate-Range Nuclear Forces Treaty, the first agreement to actually ban a whole category of nuclear weapons.
15
01/04/199010In late 1989, the Berlin Wall falls, symbolically ending the Cold War. "Forty-four years after Winston Churchill's 'Iron Curtain' speech, the myth of monolithic communism has been shattered for all to see."
16
01/12/199117With the Cold War officially over, the United States and Russia begin making deep cuts to their nuclear arsenals.
17
01/12/199514Hopes for a large post-Cold War peace dividend and a renouncing of nuclear weapons fade.
18
01/09/19989India and Pakistan stage nuclear weapons tests only three weeks apart. "The tests are a symptom of the failure of the international community to fully commit itself to control the spread of nuclear weapons – and to work toward substantial reductions in the numbers of these weapons."
19
27/02/20027Concerns regarding a nuclear terrorist attack underscore the enormous amount of unsecured–and sometimes unaccounted for–weapon-grade nuclear materials located throughout the world.
20
12/01/20075The world stands at the brink of a second nuclear age. The United States and Russia remain ready to stage a nuclear attack within minutes, North Korea conducts a nuclear test, and many in the international community worry that Iran plans to acquire the Bomb.
21
18/03/20106Talks between Washington and Moscow for a follow-on agreement to the Strategic Arms Reduction Treaty are nearly complete, and more negotiations for further reductions in the U.S. and Russian nuclear arsenal are already planned.
22
11/01/20125"The challenges to rid the world of nuclear weapons, harness nuclear power, and meet the nearly inexorable climate disruptions from global warming are complex and interconnected. In the face of such complex problems, it is difficult to see where the capacity lies to address these challenges.”
