at the end of the second world war
00:00:14
the cold war had begun the world lay
00:00:16
divided between two great superpowers
00:00:19
the united states and the soviet union
00:00:22
it would not be a conventional war with
00:00:24
the two sides never directly fighting
00:00:27
instead it would be an ideological
00:00:29
battle between communism
00:00:30
and capitalism the east first the west
00:00:33
and the resulting struggle for
00:00:35
ideological influence
00:00:36
and power both sides would stockpile
00:00:39
nuclear weapons
00:00:41
with questions over how to use control
00:00:43
and eliminate them
00:00:44
becoming central to the conflict from
00:00:47
stalin to reagan
00:00:49
from the arms race to the cuban missile
00:00:51
crisis
00:00:52
from the berlin wall to vietnam and
00:00:54
korea
00:00:55
this is the story of the cold war
00:01:01
[Music]
00:01:07
at the end of the second world war
00:01:09
europe lay divided between two camps the
00:01:12
soviet union
00:01:13
the world's leading communist power
00:01:15
would rule over what would become known
00:01:17
as the eastern bloc
00:01:18
after suffering almost 27 million
00:01:21
casualties during the war
00:01:23
soviet leader joseph stalin had been
00:01:25
keen to create a buffer zone against the
00:01:27
west
00:01:28
installing communist governments across
00:01:30
eastern europe
00:01:31
as former british prime minister winston
00:01:33
churchill would famously state
00:01:35
an iron curtain has descended across the
00:01:37
continent
00:01:39
the united states the world's leading
00:01:41
capitalist power
00:01:42
would also emerge as a post-war
00:01:44
superpower
00:01:45
their economy was thriving and they had
00:01:48
sole control of the most powerful weapon
00:01:50
in human history
00:01:51
the atomic bomb two of which president
00:01:54
harry truman had dropped on japan to end
00:01:56
the war
00:02:03
hostilities began when stalin delayed
00:02:06
the removal of soviet troops from iran
00:02:08
and pressured turkey into giving him
00:02:10
control over the turkish straits
00:02:12
wanting to stop soviet expansionism
00:02:15
president truman would announce the
00:02:16
truman doctrine
00:02:18
sending military aid to greece and
00:02:20
turkey
00:02:21
it was a policy aimed at containing the
00:02:23
soviet union
00:02:24
and would become the basis of american
00:02:26
cold war strategy for years to come
00:02:29
this policy was known as containment
00:02:32
fearing the spread of communism in
00:02:34
europe the united states would
00:02:36
also introduce the marshall plan in
00:02:38
april 1948.
00:02:40
it was thought that by improving
00:02:41
europe's economies communism would lose
00:02:43
its appeal
00:02:44
the plan provided almost 13 billion
00:02:47
dollars of financial aid
00:02:48
encouraging economic integration and the
00:02:50
promotion of free markets
00:02:56
germany was one of the most prominent
00:02:58
symbols of the newly divided world
00:03:00
having been split in half after the war
00:03:03
the soviets would occupy the east
00:03:05
with britain france and america
00:03:07
occupying the west
00:03:09
berlin despite laying 100 miles within
00:03:12
the soviet zone
00:03:13
was divided in the same way in june 1948
00:03:17
stalin would begin the berlin blockade
00:03:19
stopping all ground access to the city
00:03:22
in an attempt to drive out the americans
00:03:24
british and french
00:03:25
but truman quickly responded beginning
00:03:28
the berlin airlift
00:03:29
delivering supplies to the city for 15
00:03:31
months and forcing stalin to end at the
00:03:33
blockade
00:03:35
with tensions high the us and its allies
00:03:37
would establish an independent west
00:03:39
german state
00:03:40
the federal republic of germany the
00:03:43
soviets would respond
00:03:44
the following month by creating the
00:03:46
german democratic republic
00:03:47
in the east in response to soviet
00:03:50
expansion and influence
00:03:52
nato the north atlantic treaty
00:03:54
organization
00:03:55
was created in 1949 bringing together
00:03:58
the us
00:03:59
canada and most of western europe in a
00:04:01
defensive pact against the soviet union
00:04:09
to help stop the spread of communism the
00:04:12
cia would be established in september
00:04:14
1947
00:04:15
with the organization growing in size
00:04:17
and strength over the coming years
00:04:20
from 1949 to 1952
00:04:23
cia personnel would increase tenfold
00:04:25
with their overseas bases growing from 7
00:04:28
to 47
00:04:29
and their annual budget increasing from
00:04:31
4.7 million
00:04:32
to 82 million dollars they would go on
00:04:35
to interfere in developing countries
00:04:38
where independence movements were often
00:04:39
seen as potential paths to communism
00:04:42
in 1953 and 54 they would overthrow the
00:04:45
leaders of iran and guatemala
00:04:48
installing highly unpopular dictators in
00:04:50
their place
00:04:51
earning the organization an infamous
00:04:54
reputation
00:05:00
events in east asia would soon turn the
00:05:02
cold war into a global conflict
00:05:04
in china mao zedong had led communist
00:05:07
revolutionaries to victory in 1949
00:05:10
establishing the people's republic of
00:05:12
china
00:05:13
the u.s would respond by increasing
00:05:15
economic support to its new ally japan
00:05:18
in an attempt to stimulate economic
00:05:20
growth in the region
00:05:21
as well as sending aid to french
00:05:23
colonial forces in vietnam
00:05:25
who were fighting against a communist
00:05:26
independence movement
00:05:28
led by ho chi minh in 1950
00:05:32
communist north korea invaded south
00:05:34
korea
00:05:35
with domino theory at the height of
00:05:37
political thought the idea that if one
00:05:39
nation fell to communism
00:05:40
others would as well the united states
00:05:43
sent tens of thousands of american
00:05:44
troops to push the invaders back
00:05:46
north the korean war would drag on for
00:05:49
three years
00:05:50
with the armistice of july 1953 leaving
00:05:53
it so there was no clear victory for
00:05:55
either side
00:05:56
the border between the two careers had
00:05:58
hardly shifted at all
00:06:00
with the loss of life totaling over two
00:06:02
million
00:06:03
but crucially the korean war showed that
00:06:05
communism could be contained
00:06:07
the main thinking behind future
00:06:09
conflicts in particular
00:06:11
vietnam
00:06:17
after stalin's death in 1953 nikita
00:06:20
khrushchev had become leader
00:06:22
soon creating the warsaw pact to counter
00:06:25
the growing power of nato
00:06:27
but khrushchev would soon prove to be a
00:06:29
provocative and unpredictable leader
00:06:31
in november 1956 he would threaten
00:06:34
britain and france with rocket weapons
00:06:36
after they invaded egypt and he was
00:06:38
known for his emotional outbursts
00:06:40
allegedly banging his shoe on a table at
00:06:42
the 1960 united nations general assembly
00:06:46
when a new president john f kennedy came
00:06:48
to power in 1961
00:06:50
khrushchev made an attempt to secure
00:06:52
berlin
00:06:53
there had been around 2.7 million
00:06:55
defections from communist east germany
00:06:58
since 1949 most of which had escaped
00:07:01
through west berlin
00:07:02
securing the city was therefore vital to
00:07:04
the survival of the german democratic
00:07:06
republic
00:07:07
with defections usually of the highly
00:07:09
trained and educated
00:07:10
growing by the day at a 1961 meeting in
00:07:14
vienna
00:07:15
khrushchev gave kennedy six months to
00:07:17
vacate berlin
00:07:18
but kennedy refused now desperate
00:07:21
khrushchev authorized the construction
00:07:23
of the berlin wall
00:07:24
on august 12 1961 creating a physical
00:07:28
barrier between east and west berlin
00:07:31
starting as a barbed wire fence it soon
00:07:33
turned into a massive concrete block
00:07:35
wall
00:07:36
12 feet high and nearly 100 miles long
00:07:39
complete with armed guards and
00:07:40
minefields it was an embarrassment for
00:07:43
communists
00:07:44
everywhere
00:07:44
[Music]
00:07:50
[Music]
00:07:51
but kennedy was having difficulties of
00:07:53
his own cuba had been taken over by
00:07:56
communist revolutionaries in early 1959
00:07:59
led by fidel castro the revolutionaries
00:08:02
began freeing cuba of its economic and
00:08:04
political reliance on the us
00:08:06
eventually turning to the soviet union
00:08:08
for help
00:08:10
not wanting a communist nation so close
00:08:12
to home
00:08:13
kennedy attempted to topple castro from
00:08:15
power in the bay of pigs invasion
00:08:17
using a group of cia-trained cuban
00:08:20
exiles
00:08:21
but it would turn out to be a disaster
00:08:23
with the invaders surrendering
00:08:25
after just three days it was an
00:08:27
embarrassment to kennedy
00:08:28
and convinced khrushchev that he needed
00:08:30
to protect castro
00:08:32
with him sending nuclear missiles to the
00:08:33
island in 1962
00:08:36
american reconnaissance aircraft soon
00:08:38
spotted the missiles
00:08:40
causing kennedy to begin a naval
00:08:42
blockade of cuba to prevent any further
00:08:44
soviet shipments from arriving
00:08:47
a hundred and forty thousand u.s
00:08:48
invasion troops were then stationed in
00:08:50
florida
00:08:51
and the u.s alert system was raised to
00:08:53
defcon 2 for the first time in history
00:08:56
they were preparing for nuclear war
00:08:58
[Music]
00:08:59
as negotiations were underway a
00:09:02
confrontation in the atlantic
00:09:03
almost ended in disaster u.s ships had
00:09:06
used signaling depth
00:09:08
charges to alert a soviet submarine that
00:09:10
it had strayed too close to the blockade
00:09:13
thinking they were under attack the
00:09:15
submarine's captain ordered nuclear
00:09:17
torpedoes to be launched
00:09:18
but the decision required the approval
00:09:20
of all three onboard officers
00:09:23
one of the officers vasily arkipov
00:09:26
refused to go through with the launch
00:09:28
single-handedly preventing the outbreak
00:09:30
of a nuclear war
00:09:32
the very next day on october 28th
00:09:35
kennedy and khrushchev were able to come
00:09:37
to an agreement
00:09:38
kennedy promised not to invade cuba and
00:09:40
khrushchev removed the soviet missiles
00:09:43
it was the closest the world has ever
00:09:45
come to nuclear war
00:09:46
and it significantly impacted the
00:09:48
outlook of both powers
00:09:50
with a hotline being installed between
00:09:52
the white house and the kremlin
00:09:53
to provide better communication if
00:09:55
another crisis occurred
00:10:02
the next major crisis would occur in
00:10:04
vietnam where the u.s had been
00:10:06
supporting the south in their struggle
00:10:08
against the communist north for almost a
00:10:10
decade
00:10:11
after kennedy's assassination in 1963
00:10:14
his vice president
00:10:15
lyndon b johnson was left to deal with
00:10:17
vietnam
00:10:18
believing america would look weak on the
00:10:20
international stage if he allowed the
00:10:22
south to fall to communism
00:10:24
johnson chose to rapidly increase u.s
00:10:26
military involvement
00:10:28
but the war was deeply unpopular and in
00:10:30
1968 protests would break out across the
00:10:33
western world
00:10:34
the largest would be seen in america
00:10:36
where a politicized youth demonstrated
00:10:38
against a war they thought unjust and
00:10:40
unwinnable
00:10:42
the scale of discontent proved too much
00:10:44
for johnson
00:10:45
who decided not to seek re-election the
00:10:48
war would last for another five years
00:10:50
before the us decided to withdraw
00:10:52
with the communist north then taking
00:10:54
over the south
00:10:55
more than 58 000 americans had died as
00:10:58
well as 250 000
00:11:00
south vietnamese soldiers over a million
00:11:03
north vietnamese soldiers and vietcong
00:11:05
gorillas would also perish
00:11:07
as well as over 2 million civilians from
00:11:09
both the north and the south
00:11:10
and thousands more from laos and
00:11:12
cambodia while containment had worked in
00:11:15
korea
00:11:16
it had proven ineffective in vietnam
00:11:24
by 1964 the soviet union had been going
00:11:27
through several
00:11:28
internal difficulties khrushchev had
00:11:30
been deposed and replaced by leonid
00:11:32
brezhnev
00:11:33
whose reign was marked by nepotism
00:11:35
corruption and economic stagnation
00:11:38
standards of living within the soviet
00:11:40
sphere were deteriorating
00:11:42
and disillusionment was growing with the
00:11:44
brezhnev doctrine suppressing dissidents
00:11:46
throughout the region with military
00:11:48
force
00:11:49
this would lead brezhnev to seek a more
00:11:51
stable soviet american relationship
00:11:54
facing large protests over vietnam and
00:11:57
cambodia
00:11:58
president richard nixon was also looking
00:12:00
to stabilize relations
00:12:02
in late 1969 he began talks with
00:12:04
brezhnev about a strategic arms
00:12:06
limitation treaty
00:12:08
or salt which would freeze the existing
00:12:10
number of intercontinental ballistic
00:12:12
missiles on both sides
00:12:14
it was the beginning of a period of
00:12:16
detente a french term that refers to the
00:12:19
easing of tensions between nations
00:12:22
ditant would lead to a tense but
00:12:23
relatively stable decade
00:12:25
during which both sides would attempt to
00:12:27
control their nuclear arsenals and avoid
00:12:29
proxy conflicts
00:12:31
but it would ultimately prove
00:12:36
unsuccessful
00:12:40
when ronald reagan assumed the
00:12:41
presidency in 1981
00:12:43
the conventional wisdom of how to deal
00:12:45
with the soviet union
00:12:46
was falling apart dayton was not working
00:12:50
in 1977 the soviets had placed ss-20
00:12:54
ballistic missiles in eastern europe
00:12:56
and had invaded afghanistan in 1979
00:13:00
fiery speeches would become a trademark
00:13:02
of reagan with him describing the soviet
00:13:04
union as an evil
00:13:06
empire and declaring that democracy will
00:13:08
leave marxism leninism
00:13:10
on the ash heap of history but reagan's
00:13:13
view on nuclear weapons was clear
00:13:15
he wanted to see a world in which they
00:13:16
did not exist and where nations were
00:13:18
free from the threat of total
00:13:20
annihilation
00:13:21
the only way he saw to achieve this was
00:13:23
to force the soviets into a new arms
00:13:25
race they would lose
00:13:27
pressuring them to accept an arms
00:13:29
reduction agreement
00:13:30
as reagan stated their choice is to
00:13:33
break their backs to keep up
00:13:34
or to agree to reductions this policy
00:13:37
would be called peace
00:13:38
through strength the cornerstone of this
00:13:41
policy was the strategic defense
00:13:44
initiative
00:13:44
or sdi nicknamed star wars by the media
00:13:48
the project aimed at creating a radical
00:13:50
new missile defense system
00:13:52
using lasers and space-based missile
00:13:54
systems that could defend against a
00:13:56
nuclear attack
00:13:58
reagan knew that the soviet union was
00:13:59
lagging far behind in computer
00:14:01
technology
00:14:02
and could never hope to match the
00:14:03
programme leaving them dangerously
00:14:05
exposed
00:14:07
this policy worked as predicted with the
00:14:09
soviets soon forced to negotiate
00:14:11
meeting with the us in a 1985 summit to
00:14:14
discuss the ongoing nuclear arms race
00:14:16
[Music]
00:14:22
but this time reagan would meet with a
00:14:24
new soviet leader
00:14:26
mikhail gorbachev who would prove to be
00:14:28
one of the most important figures of the
00:14:30
entire cold war
00:14:32
facing years of economic stagnation and
00:14:35
growing discontent in eastern europe
00:14:37
gorbachev knew things had to change he
00:14:39
would introduce perestroika or
00:14:41
restructuring to reform the economy
00:14:44
and glasnost or transparency to address
00:14:46
corruption and political unrest
00:14:49
he knew that the arms race was crippling
00:14:51
the soviet economy
00:14:52
and that the only way forward was to
00:14:54
negotiate with the united states
00:14:57
gorbachev would meet with reagan on five
00:14:59
separate occasions between 1985
00:15:01
and 1988 with each meeting building
00:15:04
trust and respect between the two
00:15:07
reagan happily negotiated with such an
00:15:09
open and cooperative soviet leader
00:15:11
with the two signing the intermediate
00:15:13
nuclear forces treaty
00:15:14
on december 8 1987 banning all short and
00:15:18
intermediate range missiles
00:15:20
within three years the treaty had led to
00:15:22
the destruction of over two and a half
00:15:24
thousand
00:15:25
nuclear weapons with each side allowing
00:15:27
access to their nuclear sites to check
00:15:29
compliance it was a momentous agreement
00:15:32
being the first time both sides had
00:15:34
pledged to eliminate an entire class of
00:15:36
nuclear missile
00:15:38
but soon gorbachev's reforms would begin
