radioactive material. A fourth hydrogen bomb falls in the
Mediterranean nearby, and is not recovered until 81 days later. American Heritage article.
1967
- February - Treaty of Tlatelolco
opened for signature - forbids nuclear weapons in South America,
Central America, and the Caribbean. Nuclear powers not located in
the region agree to neither introduce nuclear weapons into the region
nor threaten nations in the region with nuclear weapons. While
most nations in the region sign immediately, several (including at least Argentina and Cuba) postpone

July 1: Nuclear Non-Proliferation Treaty(NNTP)
opens for signature, "The United States, United Kingdom, Soviet Union
and 59
other countries sign" immediately, subsequently nearly all nations join
the treaty. Takes effect in March, 1970. In the treaty,
both
nuclear-weapons states and non-nuclear-weapons states agree not to
spread nuclear weapons beyond the nuclear-weapons states of the
day. Also, nuclear-weapons states agree to negotiate in good
faith toward ending the nuclear arms race, eliminating nuclear
weapons, and moving toward a treaty on complete disarmament.
As of 2000, only Cuba, Israel, India (see 1974,1998), and Pakistan (see 1998) were not signatories. North Korea signs but later withdraws from the treaty (see 2003).

- April - Secret US State Dept. memo:
"our intelligence indicates that Israel is rapidly developing a
capability to produce and deploy nuclear weapons," despite the fact
that "Israel has said publicly ... that it will not be the first to
introduce nuclear weapons into the Middle East." Later, some will
estimate that Israel had the makings of an atomic bomb as early as
1967, which would have made it the sixth nuclear power in the
world. To this day, Israel does not publicly acknowledge that it
has nuclear weapons, despite the widespread belief that they do. (See 1975, 1986)
-
August - US Senate votes to deploy Safeguard, the successor to the Sentinel ABM system. (See also 1972, 1975, 1976)

January- Pres. Reagan takes office
- June 7 - Israeli warplanes bomb the unfinished Iraqi Osirak nuclear reactor near Baghdad. Israeli statment: "The atomic bombs which that reactor was capable of
producing whether from enriched uranium or from plutonium, would be of
the Hiroshima size. Thus a mortal danger to the people of Israel
progressively arose." Iraq denies having plans to use the reactor for weapons production.
- T.K. Jones, Deputy
Under Secretary of Defense for Research and Engineering, Strategic and Theater
Nuclear Forces, tells interviewer Robert Scheer that "nuclear war was not nearly as devastating as
we had been led to believe. He said, 'If there are enough shovels to go
around, everybody's going to make it.'
The shovels were for digging holes in the ground, which would be covered
somehow or other with a couple of doors and with three feet of dirt thrown on
top, thereby providing adequate fallout shelters for the millions who had been
evacuated from America's cities to the countryside. 'It's the dirt that
does it,' he said."
- Nov. 18: Pres. Reagan proposes the "Zero Option" for
intermediate-range nuclear forces in Europe - that both Soviet and
US/NATO IRBMs in Europe be completely eliminated. Given that the
Soviets already had many such missiles deployed and the west wouldn't
deploy modern missiles until late 1983, the
proposal was to trade existing Soviet missiles for planned US missiles,
and was consequently not well received in Moscow. The "Zero Option" was widely perceived as a propaganda ploy to reduce European resistance to the missiles' deployment. Perhaps surprisingly, it came to pass in 1987-1991.
1982
- Pres. Reagan requests $252 million for civil defense programs, to
grow to $4.3 billion over several years, including a "crisis
relocation" program - which would evacuate major American cities in
times of crisis during which nuclear attack seemed imminent.
Eventually congress allocates $144 million, but the Senate Armed
Services Committee notes that while it "continues to believe that an
increased civil defense effort is important . . . it does not believe
that the 'crisis relocation'plan will work." (From FEMA's report "AMERICAN CIVIL DEFENSE 1945 - 1984", p.22-23) (See also 1978, 1985)
- Nov. 10: Leonid Brezhnev, General Secretary of the Communist Party for the Soviet Union, dies. He is succeeded by Yuri Andropov, who lives only 15 months in office.
- December 13: James Scoville Jr., former assistant director of the
Arms Control and Disarmament Agency and deputy director for research of
the Central Intelligence Agency, writes in the New York Times that the US' planned MX missile "invites attack" by the Soviets.
1983
- March 23: President Reagan proposes a space-based defensive system against ballistic missiles, in what comes to be known as the Star Wars speech. Here are excerpts from the speech, the anti-ballistic-missile part is at the very end.
Many believe Able Archer marked the
closest the world had come to nuclear war since the Cuban Missile
Crisis in 1962.
- Nov 20 - The ABC television network airs the made-for-television movie "The Day After",
depicting the effects of a nuclear war on Lawrence, Kansas. It
was watched by 100 million viewers. ABC followed its broadcast
with a live panel discussion including science popularizer and arms
race opponent Dr. Carl Sagan, former Secretary of State Henry
Kissinger, former Secretary of Defense Robert McNamara, writer and
political commentator William F. Buckley and the then-Secretary
of State George Shultz. Director Nicholas Meyer later said that "When [Reagan] signed the Intermediate Range
Weapons Agreement at Reykjavik (in 1986) with Gorbachev, I got a
telegram from his administration that said, ‘Don't think your movie
didn't have any part of this, because it did.'" Here's a retrospective article from Lawrence, Kansas, where much of the film was set (and filmed on location). An extensive analysis from Conelrad.com.

Film Thirteen Days about the Cuban Missile Crisis is released (see 1962) The film is based at least in part on May & Zelikow's transcription
of tape recordings of Kennedy's cabinet meetings during the crisis,
recordings that were secret until ?the 70's? and not fully declassified
