Outlines
🌏 太平洋戦争の勃発
太平洋地域が緊張を高める中、日本が急速に領土拡大を進め、資源を確保し帝国を築いていく様子が描かれています。1940年代に入ると、日本はアメリカからの重要な資源である石油と金属に依存しており、アメリカは日本を警戒しながらも我慢しています。しかし、日本がナチスドイツと同盟を組んだ後、フランス植民地に進出し、アメリカの同盟国である中国との連絡を完全に遮ることになったため、アメリカは日本への資源供給を断ち切ります。これにより日本は2年以内に資源が枯渇すると予想し、急速に南東アジアの豊富な資源地帯へ進出し、欧州帝国主義からアジアを解放すると宣伝しながら、実際には自国の資源確保を図る計画を進めました。その一環として、1941年12月に真珠湾攻撃を仕掛け、アメリカを含む同盟国との戦争を引き起こしました。
🔍 ミッドウェー海戦の転機
アメリカの暗号解読チームが日本軍の作戦を事前に知り、日本軍の攻撃計画に対処する準備を整えています。4日間の激戦の末、アメリカは日本海軍を敗北させ、4つの貴重な空母を破壊しました。これは日本軍の勢いを大きく阻み、アメリカとその同盟国が太平洋戦争の潮流を変える契機となりました。アメリカは日本帝国の供給路線を狙い、戦略的島々を征服することで、日本の戦力を弱め、太平洋戦争の進展を好転させました。
🗺️ アメリカの「島跳び」戦略
アメリカ軍は太平洋戦線での進撃において、距離の大きな問題に直面しています。しかし、アメリカは日本の供給路線を標的にし、戦略的島々を征服することで日本の帝国を削る「島跳び」戦略を採用しました。この戦略により、アメリカは日本軍の強固な拠点を避けつつ、日本の供給路線を断つことで、日本の戦力を弱め、太平洋での支配力を回復させました。特に、南の重要な軍事拠点に対するアメリカの供給船攻撃は、日本軍の戦力を大幅に削ぎました。
💥 原子爆弾投下と終戦
1945年、アメリカ軍は日本本土への進攻を計画中ですが、オキナワ島の血痕累々の戦闘から、日本本土への侵攻が多大な犠牲を伴うことを認識しています。一方、ソ連は日本の降伏を求める同盟国共同声明に日本が返信しないことを拒絶と見なし、アメリカは新開発の原子爆弾を用いて戦争を迅速に終わらせることを決断します。ヒロシマとナガサキに原子爆弾を投下し、ソ連も日本に対して戦争を宣言。これにより、日本は無条件降伏を決定し、第二次世界大戦は終結しました。
🏝️ 戦後の沖縄と日本
戦後、アメリカは日本の軍事力を排除し、戦犯を処罰しました。オキナワ島にはアメリカの軍事基地が建設され、アメリカはアジアでの利益を守るために1970年代まで占領しました。現在も多くのアメリカ軍がオキナワに駐留し、日本の主要な安全保障の源となっています。この地域の緊張が再び高まっている中、日本は再び軍事力を拡大していますが、戦争の記憶は住民の心に深く刻まれています。

Transcripts
- [Reporter] It is no joke. It is a real war.
(tense music)
Japan has made a very severe attack.
- [Johnny] This region, the Pacific,
recently, it's heating up.
And now is probably a good time to rewind
and remember what this region looked like,
back when there was a war happening out here
on these islands.
A war between great powers.
Let's start right here, at the end of the 1800s,
when Japan is expanding.
Fast.
(reflective music)
Conquering territory, taking the resources,
becoming a powerful empire.
By 1940, their empire looks like this.
It includes hundreds of remote islands out here
in the Pacific.
And Japan uses these colonies to extract resources
that fed this growing conquest.
But they don't have everything they need yet.
They still rely on the US for the most vital of resources:
oil and metal.
Now, the US doesn't necessarily like
how aggressive Japan is being in their region,
but they tolerate it.
That is, until Japan allies itself with Nazi Germany
and then continues its expansion into a French colony
and threatens to completely cut off the US
from its ally, China.
So the US, along with Britain and the Netherlands,
cut Japan off of oil, gas, iron, and steel.
These are vital resources, so this is a major blow to Japan.
They calculate that they only have two more years
before they run out of this vital energy.
They must act quickly.
So they start looking further south
to land that is known to have a lot of oil.
The problem for Japan is that this is all controlled
by European empires.
Japan makes a plan to kick out all of these Europeans
and establish their own access to oil and metal
so they aren't reliant on outsiders.
And they sell this ambitious plan to their people
by saying that they actually want to liberate Asia
from European domination.
So in December 1941, they initiate this plan,
sending ships and planes to drop bombs all over the region
that they want to conquer.
And to stop the Americans
from coming to the Europeans' rescue,
Japan has already sent a large chunk of its Navy
to surprise the Americans
by bombing their Navy in Pearl Harbor, Hawaii.
It was their first step
for kicking off this larger offensive.
- [Reporter] A severe bombing of Pearl Harbor by-
- [Johnny] The attacks on Pearl Harbor
and all over Asia were a huge, bold,
and risky move for Japan.
No one thought they would do it;
it came as a massive surprise.
And as a result,
it was incredibly successful for Japan's goals:
the US and its allies are now at war.
But beating back Japan will not be easy.
Japan has a powerful Navy.
And not only is America's Pacific fleet severely damaged
because of the attack on Pearl Harbor,
but around this same time,
Hitler has taken the moment to declare war on the US,
dragging them into the European theater of World War II.
Over the next seven months, Japan takes even more territory.
- [President Roosevelt] Powerful and resourceful gangsters
have banded together to make war upon the whole human race.
Their challenge has now been flung
at the United States of America.
Together with other free peoples,
we are now fighting to maintain our right to live,
among our world neighbors, in freedom, in common decency,
without fear of assault.
We are now in this war.
- [Johnny] The US has to surrender the Philippines,
its foothold in the Pacific.
And Japan forces capture
and kill tens of thousands of American and Filipino troops
in just one of what would become many horrific war crimes
they commit during this war.
By the middle of 1942,
Japan has achieved its goals of kicking out European empires
and securing for itself a massive empire full of resources.
They're now self-sufficient, and they're growing.
And they're not done.
They're drunk on all of this success,
and some military leaders want to keep pushing east.
All the way to here,
which would cut the US off from its big ally, Australia.
So they set their sights on this American base,
located on a small atoll called Midway.
If they could take Midway, the US would be so weak,
Japan calculates, that they would be forced
to settle this conflict,
leaving Japan with all of this newly conquered territory.
Alas, that's not what happened.
In May of 1942,
Japan sends a massive fleet of hundreds of planes,
accompanied by battleships, cruisers,
destroyers, and submarines,
as well as four of their precious aircraft carriers.
Now remember, this is World War II,
and you can't really fight a war out here in the ocean
without aircraft carriers,
which enabled Japan's planes to land
and refuel while fighting deep out in this ocean.
Aircraft carriers are vital.
So Japan is preparing to conquer Midway.
But what they don't know is that American code breakers
in Hawaii have cracked Japan's encrypted communication
and are aware of their battle plans days before the attack.
This makes all the difference,
and in a four-day battle,
the US defeats Japan's Navy at Midway,
destroying all four of their precious aircraft carriers
in the process.
- [Reporter] The odds looked impossible,
but when it was all over,
the Japanese had suffered their greatest naval defeat
in history.
- It's a huge blow to Japan's momentum,
and from here, the US and its allies start
to turn the tide on this war in the Pacific.
Hey, I know we're talking about World War II,
but I just wanna pause really quick
for a message from our sponsors.
We can't make journalism
and history stories like this without sponsors.
So thank you, BetterHelp, for sponsoring today's video.
I don't know about you,
but I am someone who did not realize
that mental health was important until just a few years ago.
I knew that, like, exercise, physical exercise,
was really important for my body,
but in recent years I've learned that mental health,
the coaching and processing of your thoughts
with a professional, is just as important.
I've been in therapy for a few years now,
not because of any clinical condition,
but because I simply am a human,
who has relationships and struggles and invasive thoughts.
And with a therapist, I'm able to talk through those
in a very safe, trusting environment.
It has been a game changer for me.
BetterHelp is a platform that allows you
to access a therapist much easier
than the more traditional way.
You sign up for BetterHelp,
you take a quiz about who you are
and what you're struggling with.
And then what they do is they pair you
with a licensed therapist within their huge network
of tens of thousands of therapists.
You can be talking to a therapist really quickly,
and you can do it in whatever way
is most comfortable to you.
Text, video call, phone call, which is what I do.
I do a phone call with my therapist
while I'm walking through the forest,
which is incredibly peaceful for me.
The whole point of therapy is to find someone
that is not judging you,
but is hearing you and guiding you through your own thoughts
and your own struggles.
If your therapist isn't a good fit, with BetterHelp,
you can pretty quickly and easily switch to someone else.
Which is a big deal,
if you've ever looked for a therapist the traditional way.

Let's dive back into this map of World War II.
(tense music)
So here's a problem for both sides: distance.
It's sort of hard to fathom the distances out here.
Like, you could fit the mainland United States
in just one small part of the Japanese empire.
And remember that the US military has
to travel thousands of kilometers just to get here.
Distance is also a problem for Japan,
who, yes, just conquered all of this territory,
but that means that it now has to ship resources
back to the mainland.
It has to get men, doctors, food,
and supplies out to all of this land,
thousands of kilometers away,
creating brand-new supply routes.
We found this old Japanese map drawn up during the war
that shows all of these colonies,
shaded with a red marker,
and showing this dizzying web of supply lines needed
to keep the war going.
This was a logistical nightmare for Japan,
but it was also a key vulnerability
that the US would exploit in this conflict.
So the US begins cutting into the Japanese empire.
It's off to a slow start,
but eventually they settle onto a strategy
of targeting certain islands.
Not the ones that were the most fortified,
but the ones that would get them one step closer
to the Japanese mainland,
but also give them proximity to these supply lines.
The supply lines that keep Japan's war machine running.
The US starts conquering these lesser-fortified islands,
and using them to target the ships that carry food
and weapons and supplies throughout the Japanese empire.
I found this dataset that shows every merchant vessel
that the US and its allies sunk during these years.
It's a lot.
American submarines alone would go on to sink 5 million tons
of Japanese shipping and naval vessels.
This strategy of targeting the supply lines was
a game changer for the US,
allowing them to weaken the Japanese empire
by targeting its cargo, like they did down here
in this key Japanese military stronghold
in the south of the empire.
The US and its allies first conquered nearby islands
and then used these islands as a jumping-off point
to target the supply lines.
But instead of mounting an attack on this stronghold,
the US focused on the supply ships
that were bringing food, ammunition, reinforcements,
and medical supplies to this stronghold.
This left tens of thousands of Japanese soldiers stranded
to die of starvation and disease.
The US was able to take out a key Japanese base
without having to fight a battle.
The island hopping strategy was really working.
And if you look closely at this map,
you'll see that it allowed the US
to bypass these heavily fortified Japanese islands,
focusing more on cutting them off
than trying to conquer them,
while also getting the US closer and closer to the mainland.
As 1945 rolls around, the US continues to beat Japan back.
The two US forces converge to retake the Philippines.
All these newly captured islands allow the US
to deploy their new high-tech plane:
the B-29 bomber.
This thing could fly super high
and deep into the Japanese mainland
and drop 20,000 pounds worth of bombs.
(tense music)
Japan is clearly losing by now,
so they start to resort to more brutal tactics,
like having their pilots fly their planes
into US ships in suicide attacks.
A deadly tactic that not only led to immense damage
to the US Navy, but also had a psychological element.
A realization that the enemy was willing to go
to great lengths to fight back.
But even so, Japan's empire continued to shrink,
almost as quickly as it had expanded.
But the closer the US gets to the mainland,
the more brutal the fighting is becoming.
For a variety of reasons,
there's really only one path to invade the mainland.
You have to hop along this southern island chain
and invade from the south.
So the US sets their sights
on perhaps the most important island in the Pacific:
Okinawa.
Japan knows that the US is coming for Okinawa,
so they recruit around 40,000 local men,
giving some of them only spears to defend themselves.
Together with the army,
they dig tunnels and caves and trenches and bunkers.
The army gives out hand grenades to civilians,
telling them to commit suicide instead of surrender,
warning them that the Americans will be brutal
and violent to anyone they capture.
Japan wants this battle to convince the Americans
that invading the mainland is a bad idea.
It's their last-ditch effort to avoid defeat.
The US hits the beach at Okinawa,
starting one of the bloodiest battles of the entire war.
82 days of violence that leaves a third
of the population dead.
A total of around 100,000 Japanese
in addition to 12,000 American soldiers.
And the US wins.
They now control the most valuable island of them all,
the island that will enable them to invade the mainland.
But they're also left with a horrifying clarity of
how serious Japan is about not surrendering,
about fighting until the very end.
Invading the mainland will be costly.
Meanwhile, in Europe,
Hitler and his allies have been defeated.
The winners get together and issue a statement to Japan:
unconditional surrender,
or face prompt and utter destruction.
Now that Hitler is defeated,
the Soviet Union is also preparing to join the US
to deal the final blow to Japan.
But Japan doesn't reply to the demand for surrender,
and the Allies see this as a rejection.
Back in the US, in the deserts of the Southwest,
the US has just successfully tested an atomic bomb.
So now they have a decision to make.
They either continue their momentum
and invade the mainland of Japan
and face not only Japanese soldiers,
but civilian militias of potentially tens
of millions of citizens ready to fight.
And it would also involve the Soviet Union participating,
which means if they won the war with the Soviet's help,
they would have to split control
and influence over Japan's empire after the war.
Or the second option was to use their new powerful bomb
to swiftly end the war,
with no more loss of American lives
and much less Soviet influence in post-war Japan.
They could do it on their own
while also sending a message to the Soviets
that they were the most powerful.
On August 6th, 1945, they chose the second plan.
(otherworldly music)
They dropped this unfathomably powerful bomb
on the city of Hiroshima,
releasing a hellfire the world had never seen
and killing 140,000 people,
almost all of them civilians,
forever altering the course of history.
Two days later, the Soviet Union declared war on Japan
and began rapidly taking their territory.
When Japan still doesn't surrender,
the US drops another bomb.
This one on the city of Nagasaki.
The Soviets continue to rapidly take territory,
and it's more clear than ever that it is over for Japan.
While some factions of the Japanese army still don't want
to surrender, the emperor goes around them
and tells the nation that it's over.
Japan is unconditionally surrendering.
The Americans moved in,
took away Japan's powerful military,
prosecuted the war criminals,
and sent tens of thousands of troops
to the vital island of Okinawa,
where the US stayed as the occupying power until the 1970s,
and where they still have tens of thousands of troops
that serve American interests in Asia,
while also being Japan's main source of security.
The memory of this war is still
in the minds of the people here,
especially for those in the cities that were bombed
and the southern islands that were invaded.
And as this region becomes tense again,
Japan is now expanding its military once again.
Mostly down here on these vital islands.
I traveled here to see what that looks like
and to talk to the people about what this feels like,
what they're worried about.
And I'll be sharing that story in an upcoming video.
- Let's pray that peace be now restored
to the world,
and that God will preserve it always.
These proceedings are closed.
