[TYPING] [MUSIC] Good morning,
-
good afternoon, whatever
-
time of the day it is.
-
Thank you for checking
-
out the video today.
-
We're breaking down World War II.
-
If you're studying this topic for APUSH or
-
regular U.S. History,
-
this video is gonna help you out.
-
Now remember, on December 7th, 1941,
-
all of that isolationist sentiment goes
-
out the window with the
-
attack on Pearl Harbor.
-
It effectively ends
-
the isolationist movement.
-
December 8th, Congress declares war.
-
Three days later, Germany and Italy
-
declare war against the United States.
-
And what you see is the U.S. had already
-
begun mobilizing for war
-
even before this attack on December 7th.
-
For example, we had the Selective Service
-
Act, or the first peacetime draft.
-
We had Lend-Lease supplies
-
being produced for the Allies.
-
And as a result of this, many US factories
-
had already shifted to war production.
-
Once we enter the war,
-
we are now a member of the Allies,
-
the Big Three, England, the Soviet Union,
-
and the United States, but don't forget,
-
there are many other countries
-
fighting along for the Allied cause.
-
It's important to note that the role of
-
the federal government is going to expand.
-
In fact, it expanded greater than it
-
had during the New Deal or World War I.
-
This is a mass mobilization
-
to fight this war.
-
World War II brought about a huge
-
mobilization on the home front.
-
This is a mass mobilization, and really,
-
it's gonna be industrial production
-
of the United States that is going
-
to be a key factor for the Allied victory.
-
And of course, as a result of this mass
-
mobilization, the smiley face comes out,
-
the Great Depression ends.
-
And you could see the unemployment rate
-
drop even before Pearl Harbor, but it
-
only continues to drop throughout the war.
-
Now, what do we mean mass mobilization?
-
Well, the federal government
-
is gonna play a key role.
-
For example, you have, just like
-
during World War I, different agencies.
-
The War Productions Board allocated
-
resources for the war effort,
-
making sure that we go from consumer
-
production to war production.
-
The Office of Price Administration froze
-
prices and wages and rationed certain
-
goods, such as meat, gas, sugar, and so on,
-
so that there would be enough
-
material for the war effort.
-
Citizens received ration books for things
-
like gasoline and needed stamps in order
-
to purchase certain scarce items.
-
A black market did develop for certain
-
goods, but the OPA tried to do its best.
-
We've already said this,
-
but it's important to repeat.
-
America's industrial output was a huge
-
factor in the eventual Allied victory.
-
U.S. Factories are supplying these
-
weapons for most of the Allies.
-
Another government agency that's important
-
to know about is the Office
-
of Research and Development.
-
And what this federal agency did is it
-
contracted with scientists
-
and universities to help develop
-
technology for the war effort.
-
So, developments in sonar, radar, rockets,
-
and other things, technological advances
-
are gonna be hugely important,
-
once again, to the Allied victory.
-
And of course, the big one is the
-
Manhattan Project, which begins in 1942.
-
You can see its locations on that map
-
they're all across the United States.
-
This was a joint secret program
-
between the United States and England.
-
They kept the Soviets out of it,
-
even though they knew because
-
of spying, and it's headed by J.
-
Robert Oppenheimer.
-
And at the height
-
of the Manhattan Project,
-
the secret program a hundred thousand people worked
-
for it, and they're going
-
to spend $2 billion.
-
And in July of 1945, the first atomic bomb
-
will be successfully detonated
-
in the desert of New Mexico.
-
Another key thing to know about when we
-
study World War II is
-
the social impacts of the war.
-
The war is gonna present numerous
-
opportunities for women and various
-
minority groups living
-
in the United States.
-
They are gonna be able to improve their
-
socioeconomic position
-
as a result of World War II.
-
Couple of examples for African-Americans,
-
you're gonna have
-
a Second Great Migration,
-
where over a million African-Americans are
-
gonna leave the South searching
-
for jobs in war industries.
-
And we're really gonna see this growth or
-
this movement of people to northern
-
cities, but also on the West Coast
-
in places like California.
-
Unfortunately, discrimination was
-
extremely common in defense work.
-
Very often, African-Americans
-
had a limit to the number and the size
-
of the opportunities that were
-
presented, even by World War II.
-
In fact, race riots, once again,
-
just as we saw during World War I,
-
are gonna break out in 1943.
-
You have race riots breaking out
-
in cities like Detroit and New York.
-
So, racial tension accompanies
-
these opportunities as well.
-
A. Philip Randolph is an important
-
individual you should know.
-
He actually threatened
-
the administration of Franklin Roosevelt
-
to march on Washington,
-
DC if discrimination in defense work was
-
not addressed by the
-
Roosevelt administration.
-
An important milestone is reached when
-
Executive Order 8802 is finally issued
-
by Franklin Roosevelt to avoid this march,
-
and this is the first federal action
-
to promote equal opportunity
-
and to prohibit employment discrimination
-
in the US ever by the federal government.
-
Nearly a million African-Americans are
-
gonna serve in this war against
-
the fascists and the Nazi parties,
-
but even though we're fighting for these
-
ideals like democracy,
-
it's important to keep in mind,
-
African-Americans are
-
serving in segregated units.
-
But you do have some progress.
-
You have people like the Tuskegee Airmen,
-
the first African-American
-
pilots in the US Army.
-
With these opportunities comes new
-
demands from the Civil Rights Movement.
-
In fact, the Double Victory Campaign was
-
pursued during the war,
-
and what it was is calling for not only
-
a victory against fascism abroad,
-
but civil rights leaders were calling
-
for a victory against racism at home.
-
And what you see during World War II is
-
the membership in the NAACP dramatically
-
increases as more and more people are
-
putting demands on greater justice
-
in America, and you get new organizations
-
such as CORE,
-
the Congress of Racial Equality,
-
which was formed in 1942
-
to fight against discrimination.
-
So, make sure you know that World War II
-
has consequences on the home front
-
for various social groups.
-
Two other groups that you should know
-
about is the impact of the war
-
on Mexican Americans and Native Americans.
-
Don't forget, during the Great Depression,
-
there was this repatriation where
-
Mexican Americans and
-
people of Mexican descent were
-
forced out of the United States.
-
But during the war,
-
there was a demand for workers
-
in the defense industry and this provided
-
opportunities to thousands
-
of Mexican Americans getting
-
job in these defense plants.
-
Not only that, a program is introduced
-
in 1942 called the Bracero Program,
-
and this allowed Mexican farm workers
-
to come into the United States to work
-
without going through the formal
-
immigration proceedings.
-
So, during World War II,
-
you have the federal government
-
asking for and allowing Mexican immigrants
-
to come into the United States
-
to help out with the labor shortage.
-
Of course, as in all of these scenarios,
-
usually racial tensions increase during
-
these times as well, and racial tensions
-
between white soldiers,
-
especially naval officials,
-
and Mexican residents in Los Angeles lead
-
to the horrible Zoot Suit Riots in 1943,
-
where hundreds of Mexican American youth
-
wearing the Zoot Suit are beat up
-
and arrested by military
-
officials and the LAPD.
-
Native Americans have different responses
-
and opportunities to World War II as well.
-
They received opportunities just as many
-
other groups in defense
-
work and in the military.
-
In fact, the Navajo Code Talkers
-
are a key part of this story.
-
They are Navajo Native American men
-
who volunteer serving their country,
-
the United States,
-
and they use their native Navajo language
-
to communicate in the war against Japan,
-
and they used these Navajo words to help
-
out communication during the war against
-
Japan and play a very important role
-
in the fighting.
-
And one of the things that happens
-
with Native Americans is after the war is
-
over, a lot of the native people who left
-
the reservation to work in war industries
-
or to fight, about half will not
-
return to life on the reservation.
-
And finally,
-
you also have social and demographic
-
changes besides ethnic and racial,
-
and one important one to know about is
-
the role of women during World War II.
-
Over 200,000 women served in the military
-
in non-combat roles, but they're serving
-
nonetheless in the US Armed Forces.
-
They were not allowed to serve
-
in combat during the war.
-
And the big impact is this,
-
as the demand for industrial and defense
-
jobs increased, nearly five million women
-
entered the workforce during World War II.
-
Many of these women are working
-
in the shipyards and the defense plants.
-
They are women who, in many
-
cases, never worked before.
-
Many of them are married and their
-
husbands are off overseas
-
fighting, and they play a key role.
-
And the symbol of this
-
is Rosie the Riveter.
-
In spite of these opportunities,
-
women continued to receive lower the pay
-
than men and were expected
-
to leave once the war was over.
-
They were considered substitutes,
-
not replacements.
-
And another key thing regardless of race
-
or gender is you're gonna have huge
-
demographic changes occur as many people
-
head to the Midwest and also
-
the West Coast looking for defense jobs.
-
It's not just African American individuals
-
moving, but large migrations of people.
-
In fact, following World War II,
-
you're gonna have a post-war
-
migration to the Sun Belt.
-
Southern states are gonna see huge numbers
-
of people going to them and also
-
the West Coast to places like California.
-
The warm weather, the lower labor cost,
-
and the presence of defense factories are
-
gonna have this huge
-
population pull to these regions.
-
Now it's going to be the Japanese American
-
community in which World War II is gonna
-
have the biggest impact, and you're gonna
-
see the complete denial
-
of civil liberties.
-
Now don't forget, there was already a lot
-
of anti-Asian sentiment
-
in the United States,
-
nativism towards groups,
-
whether they be Japanese or Chinese.
-
The bombing of Pearl Harbor only
-
accelerates and increases that.
-
In fact, following the bombing on December
-
7th, Executive Order 9006 is passed
-
by the U.S. Government which requires
-
that all people of Japanese descent
-
on the West Coast be
-
relocated to internment camps.
-
It did not matter that many of these
-
individuals were Nisei,
-
second-generation Japanese Americans.
-
They are American citizens.
-
They own businesses.
-
They went to U.S. Public schools.
-
It was completely disregarded because
-
there was this feeling that perhaps these
-
individuals were going to be potential
-
spies for the government of Japan.
-
Now, keep in mind there is no evidence
-
of any wrongdoing of any of these
-
individuals, and over 100,000
-
Japanese Americans and people of Japanese
-
descent were relocated to one of 10
-
internment camps throughout the country.
-
Interesting to note is the large Japanese
-
population in Hawaii, where Pearl Harbor
-
actually was and where
-
the attack took place,
-
they were not evacuated because it would
-
have devastated the economy of Hawaii.
-
Japanese laborers were the key
-
group in that region.
-
There is an important lawsuit that you
-
need to know, Korematsu
-
versus the United States.
-
It goes all the way to the Supreme Court.
-
There is Fred Korematsu right there
-
and the Supreme Court upheld
-
the relocation as necessary
-
for national security.
-
And by now you should realize that during
-
times of national security threats or
-
perceived threats, especially wars,
-
individual civil liberties
-
go down and are, oftentimes, violated.
-
And another thing to keep in mind is
-
thousands of Japanese Americans,
-
many with their families in one of these
-
camps,
-
fought bravely for the United States.
-
And there's a great quote
-
by Harry Truman recognizing that bravery,
-
"You fought not only the enemy,
-
you fought prejudice at home and won."
-
Now, you don't need to know a whole lot
-
about the fighting of World War II, even
-
though it's really exciting stuff,
-
but a couple of key things here
-
to get you ready for your exam.
-
The Allies are going to focus first
-
on the European Theater of the war.
-
In fact, that was the focus following
-
Pearl Harbor even though it was Japan
-
who attacked us and a couple of key
-
moments that you should know about,
-
the Soviets finally stopped the German
-
advance at Stalingrad and start pushing
-
the Nazi army out of the Soviet Union.
-
The Allies, England and the U.S., especially,
-
focus first on North Africa and into Italy
-
as their strategy, and eventually you're
-
gonna have the second front which is gonna
-
take place on June 6th, 1944,
-
the famous D-Day invasion.
-
Now, if it was industrial production
-
of the United States that's going to play
-
a key role in the Allied victory,
-
it's also going to be
-
Allied military and political cooperation
-
that's gonna be another key factor.
-
In fact, during the war, the Big Three,
-
Roosevelt, Churchill, and Stalin,
-
are gonna meet numerous times to discuss
-
military strategy and also
-
to plan for the post-war world.
-
Couple of these conferences you should
-
know about, the first one is in January
-
of 1943, and this is the first time
-
that Roosevelt and Churchill
-
meet once we are in the war.
-
Remember, they had previously met
-
at the Atlantic Conference,
-
now they're meeting during the war,
-
and they decide on a couple of things.
-
Stalin's not there.
-
One, the war is gonna be
-
only finished with unconditional surrender
-
of the Axis powers,
-
and they choose that they're going
-
to invade Sicily and Italy first,
-
which makes Stalin not too happy because
-
he wanted relief for the Soviet,
-
the Red Army, from the German invasion.
-
Another conference to keep
-
in mind is the Tehran Conference.
-
This is the first time the Big Three meet.
-
There you see all three of them
-
there in November of 1943.
-
They decide a couple of things.
-
One, they start planning the opening
-
of the second front that Stalin really
-
wanted to relieve the Soviet Army once
-
again, and that's gonna be
-
eventually the D-Day invasion.
-
And they also talk about the fate
-
of Eastern Europe, and this is gonna
-
be a key thing in the post-war world.
-
Stalin wants to control Eastern Europe.
-
He wants to divide up Germany.
-
Churchill and Roosevelt
-
want a free Eastern Europe.
-
Conflict developing.
-
But they try to avoid it so they
-
could focus on winning the war.
-
And the big one happens in 1945,
-
the Yalta Conference.
-
Germany, it is decided,
-
will be divided into four zones, and both
-
Churchill and Roosevelt feel they got
-
Stalin to agree that there are going
-
to be free elections in Eastern Europe.
-
The third important thing to keep in mind,
-
and this one's key, is the Soviets promise
-
they will help out the U.S. against Japan
-
three months after
-
the war in Europe is over.
-
And then finally,
-
they also agree to create a new
-
international organization,
-
the United Nations.
-
Eventually, both Mussolini and Hitler are
-
defeated and the United States
-
then is able to turn its attention
-
on the war against Japan.
-
Important to keep in mind,
-
it was largely the U.S. military
-
responsible for the fight against Japan
-
during the early periods of the war.
-
And if you look at this map,
-
following Pearl Harbor,
-
Japan was really kicking some butt.
-
They occupied all
-
the territory in the orange.
-
They invaded the Philippines,
-
Indonesia, and much of Asia.
-
The strategy of the United States in this
-
early period is called island hopping.
-
Basically, the goal is really simple,
-
you strategically win control over
-
territory to get closer to mainland Japan.
-
And the idea is you skip certain islands
-
that Japan occupied and, eventually,
-
the U.S. military would get close enough
-
where they could start
-
aerial bombing of Japan.
-
In July of 1945, at the Potsdam
-
Conference, you have another meeting.
-
By this point, the war in Europe is over,
-
Roosevelt has unfortunately passed away.
-
And Truman, the new president,
-
is meeting with Joseph Stalin, and they
-
agree on one very important thing
-
that you need to know about.
-
They said, "Japan, you need to surrender
-
unconditionally or you will be destroyed."
-
While at the Potsdam Conference,
-
Truman is informed
-
that the Manhattan Project had
-
successfully detonated the first atomic
-
bomb, and on August 6th, 1945,
-
the first atomic bomb dropped
-
on the Japanese city of Hiroshima.
-
As planned and as promised
-
at the Yalta Conference, on August 8th,
-
the Soviet Union enters the war against
-
Japan, three months after Germany had
-
surrendered, and the next day,
-
on August 9th, the second atomic
-
bomb is dropped on Japan at Nagasaki.
-
Shortly thereafter, Japan does
-
surrender, and World War II ends.
-
The dropping of these two atomic bombs is
-
not without controversy, and it's important
-
you understand the different arguments for and against
-
the dropping of the bombs.
-
But key idea here, following World War II,
-
the U.S. will be the dominant political
-
and military country in the world.
-
Although we were isolationists when
-
World War II began,
-
at the end of World War II,
-
the United States is gonna play a key
-
role in the international community.
-
That's gonna do it for today.

-
There I am in Nagasaki taking a look
-
at a full-size model of the atomic bomb
-
that was dropped on the city of Nagasaki.
-
And as you can see,
-
next to my six-foot-five self,
-
it is quite a large bomb.
-
Until next time, thank you for watching.
-
Have a beautiful day.
-
Peace.
