## Summary

This video provides a concise, 15-minute overview of the Cold War, from its origins after World War II to the collapse of the Soviet Union. It covers key events, policies, and figures, including the Truman Doctrine, the Berlin Blockade, the Cuban Missile Crisis, and the Reagan-Gorbachev summits.

### Key Points

- **Origins of the Cold War** [00:12] — The Cold War began after WWII, with the world divided between the US and Soviet Union. It was an ideological battle between communism and capitalism, with nuclear weapons central to the conflict.
- **The Iron Curtain** [01:35] — Winston Churchill famously stated that 'an iron curtain has descended across the continent,' dividing Europe into Eastern and Western blocs.
- **Truman Doctrine and Containment** [02:06] — The Truman Doctrine was a policy of containment, sending military aid to Greece and Turkey to stop Soviet expansionism.
- **The Marshall Plan** [02:34] — The Marshall Plan provided almost $13 billion to improve European economies, with the idea that communism would lose its appeal.
- **Berlin Blockade and Airlift** [03:17] — Stalin began the Berlin Blockade in June 1948, stopping all ground access to the city. The US responded with the Berlin Airlift, delivering supplies for 15 months.
- **Creation of NATO** [03:58] — NATO was created in 1949 as a defensive pact against the Soviet Union, bringing together Canada and most of Western Europe.
- **CIA Expansion and Covert Operations** [04:12] — The CIA grew tenfold from 1949 to 1952, with its budget increasing from $4.7 million to $82 million. It interfered in Iran and Guatemala, overthrowing leaders and installing dictators.
- **Communism in Asia** [05:02] — Mao Zedong's victory in China in 1949 led the US to increase support for Japan and aid the French in Vietnam against Ho Chi Minh's communist movement.
- **The Korean War** [05:32] — The Korean War (1950-1953) showed that communism could be contained, but the border hardly shifted and over two million lives were lost.
- **The Berlin Wall** [07:14] — Khrushchev authorized the construction of the Berlin Wall in 1961 to stop defections from East Germany. It became a 12-foot-high, 100-mile-long barrier.
- **Cuban Missile Crisis** [08:40] — The Cuban Missile Crisis in 1962 brought the world to the brink of nuclear war. A Soviet submarine officer, Vasily Arkhipov, refused to launch a torpedo, preventing a nuclear exchange.
- **The Vietnam War** [10:18] — The Vietnam War proved containment ineffective, with over 58,000 American deaths and millions of Vietnamese casualties. It led to widespread protests and Johnson's decision not to seek re-election.
- **Détente and SALT** [11:57] — Détente, a period of easing tensions, led to the SALT treaty freezing ICBM numbers. However, it proved temporary.
- **Reagan's Escalation** [13:37] — Reagan's 'peace through strength' policy, including the Strategic Defense Initiative (SDI), forced the Soviets into an arms race they couldn't win.
- **Gorbachev's Reforms and Soviet Collapse** [14:37] — Gorbachev introduced perestroika (restructuring) and glasnost (transparency), leading to the INF Treaty and eventually the collapse of the Soviet Union in 1991.

## Transcript

at the end of the second world war the cold war had begun the world lay divided between two great superpowers the united states and the soviet union it would not be a conventional war with the two sides never directly fighting
battle between communism and capitalism the east first the west ideological influence and power both sides would stockpile
nuclear weapons with questions over how to use control and eliminate them becoming central to the conflict from stalin to reagan from the arms race to the cuban missile
from the berlin wall to vietnam and korea korea this is the story of the cold war
europe lay divided between two camps the soviet union the world's leading communist power would rule over what would become known as the eastern bloc after suffering almost 27 million
casualties during the war soviet leader joseph stalin had been west installing communist governments across as former british prime minister winston churchill would famously state
an iron curtain has descended across the continent capitalist power would also emerge as a post-war their economy was thriving and they had
in human history the atomic bomb two of which president harry truman had dropped on japan to end the war
the removal of soviet troops from iran and pressured turkey into giving him control over the turkish straits wanting to stop soviet expansionism truman doctrine sending military aid to greece and
it was a policy aimed at containing the soviet union and would become the basis of american cold war strategy for years to come this policy was known as containment fearing the spread of communism in
europe the united states would also introduce the marshall plan in it was thought that by improving europe's economies communism would lose its appeal the plan provided almost 13 billion
encouraging economic integration and the promotion of free markets symbols of the newly divided world having been split in half after the war
the soviets would occupy the east with britain france and america occupying the west berlin despite laying 100 miles within the soviet zone was divided in the same way in june 1948
stalin would begin the berlin blockade stopping all ground access to the city in an attempt to drive out the americans british and french but truman quickly responded beginning the berlin airlift
delivering supplies to the city for 15 months and forcing stalin to end at the blockade with tensions high the us and its allies german state the federal republic of germany the
the following month by creating the german democratic republic in the east in response to soviet expansion and influence organization was created in 1949 bringing together
canada and most of western europe in a defensive pact against the soviet union
1947 with the organization growing in size and strength over the coming years from 1949 to 1952 cia personnel would increase tenfold with their overseas bases growing from 7
and their annual budget increasing from 4.7 million to 82 million dollars they would go on to interfere in developing countries where independence movements were often seen as potential paths to communism
in 1953 and 54 they would overthrow the leaders of iran and guatemala installing highly unpopular dictators in their place earning the organization an infamous reputation
cold war into a global conflict in china mao zedong had led communist revolutionaries to victory in 1949 establishing the people's republic of the u.s would respond by increasing economic support to its new ally japan
growth in the region as well as sending aid to french who were fighting against a communist independence movement independence movement led by ho chi minh in 1950
korea with domino theory at the height of nation fell to communism others would as well the united states troops to push the invaders back north the korean war would drag on for
three years with the armistice of july 1953 leaving either side the border between the two careers had hardly shifted at all with the loss of life totaling over two
but crucially the korean war showed that communism could be contained the main thinking behind future conflicts in particular conflicts in particular vietnam
khrushchev had become leader soon creating the warsaw pact to counter the growing power of nato but khrushchev would soon prove to be a provocative and unpredictable leader in november 1956 he would threaten
britain and france with rocket weapons after they invaded egypt and he was known for his emotional outbursts allegedly banging his shoe on a table at allegedly banging his shoe on a table at the 1960 united nations general assembly
when a new president john f kennedy came to power in 1961 berlin there had been around 2.7 million defections from communist east germany since 1949 most of which had escaped
securing the city was therefore vital to the survival of the german democratic with defections usually of the highly trained and educated trained and educated growing by the day at a 1961 meeting in
khrushchev gave kennedy six months to vacate berlin but kennedy refused now desperate khrushchev authorized the construction of the berlin wall on august 12 1961 creating a physical
barrier between east and west berlin starting as a barbed wire fence it soon wall 12 feet high and nearly 100 miles long complete with armed guards and minefields it was an embarrassment for
everywhere [Music] but kennedy was having difficulties of his own cuba had been taken over by
communist revolutionaries in early 1959 led by fidel castro the revolutionaries began freeing cuba of its economic and political reliance on the us eventually turning to the soviet union for help
to home kennedy attempted to topple castro from power in the bay of pigs invasion using a group of cia-trained cuban but it would turn out to be a disaster with the invaders surrendering
embarrassment to kennedy and convinced khrushchev that he needed with him sending nuclear missiles to the island in 1962 american reconnaissance aircraft soon spotted the missiles
causing kennedy to begin a naval blockade of cuba to prevent any further soviet shipments from arriving a hundred and forty thousand u.s florida and the u.s alert system was raised to
defcon 2 for the first time in history they were preparing for nuclear war as negotiations were underway a confrontation in the atlantic almost ended in disaster u.s ships had
used signaling depth charges to alert a soviet submarine that it had strayed too close to the blockade thinking they were under attack the torpedoes to be launched but the decision required the approval
of all three onboard officers one of the officers vasily arkipov refused to go through with the launch single-handedly preventing the outbreak of a nuclear war the very next day on october 28th
to an agreement kennedy promised not to invade cuba and khrushchev removed the soviet missiles it was the closest the world has ever and it significantly impacted the outlook of both powers
the white house and the kremlin to provide better communication if to provide better communication if another crisis occurred
vietnam where the u.s had been supporting the south in their struggle decade after kennedy's assassination in 1963 lyndon b johnson was left to deal with vietnam
believing america would look weak on the international stage if he allowed the south to fall to communism johnson chose to rapidly increase u.s military involvement but the war was deeply unpopular and in
1968 protests would break out across the western world the largest would be seen in america where a politicized youth demonstrated against a war they thought unjust and unwinnable
for johnson who decided not to seek re-election the war would last for another five years before the us decided to withdraw over the south more than 58 000 americans had died as
well as 250 000 south vietnamese soldiers over a million north vietnamese soldiers and vietcong gorillas would also perish both the north and the south and thousands more from laos and
cambodia while containment had worked in korea korea it had proven ineffective in vietnam
internal difficulties khrushchev had been deposed and replaced by leonid whose reign was marked by nepotism corruption and economic stagnation standards of living within the soviet sphere were deteriorating
and disillusionment was growing with the brezhnev doctrine suppressing dissidents force this would lead brezhnev to seek a more stable soviet american relationship facing large protests over vietnam and
president richard nixon was also looking to stabilize relations in late 1969 he began talks with brezhnev about a strategic arms limitation treaty or salt which would freeze the existing
number of intercontinental ballistic missiles on both sides it was the beginning of a period of detente a french term that refers to the easing of tensions between nations ditant would lead to a tense but
relatively stable decade during which both sides would attempt to control their nuclear arsenals and avoid proxy conflicts proxy conflicts but it would ultimately prove
presidency in 1981 the conventional wisdom of how to deal with the soviet union was falling apart dayton was not working was falling apart dayton was not working in 1977 the soviets had placed ss-20
ballistic missiles in eastern europe and had invaded afghanistan in 1979 fiery speeches would become a trademark of reagan with him describing the soviet union as an evil empire and declaring that democracy will
leave marxism leninism on the ash heap of history but reagan's he wanted to see a world in which they did not exist and where nations were annihilation the only way he saw to achieve this was
to force the soviets into a new arms race they would lose reduction agreement as reagan stated their choice is to break their backs to keep up or to agree to reductions this policy
would be called peace through strength the cornerstone of this initiative or sdi nicknamed star wars by the media the project aimed at creating a radical new missile defense system
using lasers and space-based missile systems that could defend against a reagan knew that the soviet union was lagging far behind in computer and could never hope to match the programme leaving them dangerously
exposed this policy worked as predicted with the soviets soon forced to negotiate meeting with the us in a 1985 summit to discuss the ongoing nuclear arms race [Music]
new soviet leader mikhail gorbachev who would prove to be one of the most important figures of the entire cold war facing years of economic stagnation and growing discontent in eastern europe
gorbachev knew things had to change he would introduce perestroika or restructuring to reform the economy and glasnost or transparency to address corruption and political unrest he knew that the arms race was crippling
and that the only way forward was to negotiate with the united states gorbachev would meet with reagan on five separate occasions between 1985 and 1988 with each meeting building trust and respect between the two
reagan happily negotiated with such an open and cooperative soviet leader nuclear forces treaty on december 8 1987 banning all short and intermediate range missiles within three years the treaty had led to
thousand nuclear weapons with each side allowing access to their nuclear sites to check compliance it was a momentous agreement being the first time both sides had pledged to eliminate an entire class of
nuclear missile but soon gorbachev's reforms would begin to unravel the soviet union itself in december 1988 he would make a speech vowing to cut the soviet ground force commitment in eastern europe by half a
signaling that the brezhnev doctrine would no longer be enforced by the soviet military reformers began to emerge across eastern europe and in 1989 a string of democratic revolutions would
see nearly every communist government ousted from power on november the most symbolic monument of the cold war the berlin wall would come down and germany itself would be reunited the following year
the soviet union would collapse in 1991 dissolving into 15 independent states a surprisingly quick and bloodless conclusion to the cold war international relations for over 40 years
for over 40 years [Music]
