- The Atomic Bombings of Hiroshima and Nagasaki:
On August 6, 1945, the Enola Gay dropped the atomic bomb "Little Boy" on Hiroshima, causing massive devastation. Despite the destruction, Japan did not immediately surrender. On August 9, 1945, another atomic bomb "Fat Man" was dropped on Nagasaki, leading to Japan's eventual surrender and the end of World War II.
However, the events leading up to the dropping of these atomic bombs are more complex and rooted in a secret project initiated in 1942. At that time, Nazi Germany controlled much of Europe. Meanwhile across the Atlantic, 130,000 people, including scientists, engineers, and construction workers, were engaged in a secret project with a 2-billion-dollar budget. This project, known as the Manhattan Project, aimed to develop the first nuclear weapons.
Most workers were unaware of the project's ultimate goal due to high secrecy. From 1942 to 1946, the project was led by Major General Leslie Groves, while physicist J. Robert Oppenheimer directed the Los Alamos Laboratory, where the atomic bombs were designed.
Initially, they worked on a plutonium-based gun-type weapon, Thin Man. By April 1944, they realized it would not work due to spontaneous fission. They then focused on an implosion-type weapon, Fat Man, and a uranium-235 gun-type weapon, Little Boy.
On July 16, 1945, the first nuclear test, named Trinity, took place. The successful test influenced President Truman's decisions at the Potsdam Conference. Japan was given an ultimatum to surrender or face "Prompt and utter destruction".

Please quit with these scripted fiction narratives you know nukes don't exist
Read the book "Atomic Bomb Secrets" by David J Dionisi.
You will be shocked.

War is disgusting.
This video is truly eye-opening! Learning about the Emperor and his cabinet roles in the events was incredibly enlightening. Thanks for sharing!
watch the video "no, we didnt have to nuke japan"
@@kaganyuksel-xq1yo No, japan did not have to attack Pearl harbor, nor China, nor korea, nor the Philippines. Japan did not have to torture and murder surrendered soldiers AND civilians either. But japan did do these things.
@kaganyuksel-xq1yo
No thanks.
The US did what they had to, to end the war before several million more were killed (in an invasion).
And no, the emperor and military hiarchy were not willing to surrender. They were planning on sacrificing the population to protect his throne, until the very end.
@@davidgenie-ci5zl i see where youre coming from bro, but nearly all these casualties were civilians who had nothing to do with the war. On top of that we were doing that same shit just not at such a disgusting degree.
@@braydonrr It is estimate that if we did not drop the bombs, perhaps 100,000 American casualties and 1,000,000 japanese will result if we invaded to stop japan. japanese "civilians" were training to fight, even japanese children. We saw that behavior in Okinawa already. How long should we let japan hold on? The japs still held large areas of china, and Korea, were surrendered civilains were systematically raped, torture, murdered. Jaopan was testing bio and chemical weapons on chinese civilians, with plans to use it to stay in the fight.
Sure some innocents died in the atomic bombings, but the number that died palls in comparison to the number of japanese and non japanese civilians that would have died otherwise. Keep in mind that most of our troops were civilians before the war started.
It was imperative to stop japan as quick as possible, How many Korean, chinese civilians should face torture, rape, death while awaiting a slow end to the war?
The cities bombed by our nukes had military facilities and military weapons production in them too.
Blame for the deaths goes directly to japans leaders. sucks to have bad evil leaders, but we didnt put those leaders in place. They had to be stopped. The bombs saved many lives, including japanese lives.
War kills innocent civilians not the ones in power or the egoistic evil rulers that declare such brutal act to remain in power.
Absolutely
Japan was really vicious to the Chinese in WW2……they killed thousands as punishment for helping the Doolittle Raiders…..not to mention the Chinese women abducted to b ‘comfort’ workers for the Japanese soldiers…n to add insult to injury, refused Japanese citizenship to children born to these kidnapped wimen…
Yep you are absolutely correct, it’s always the innocent who suffer the most, I so hate war!!
Are you crying for the 300,000 men WOMEN and CHILDREN SLAUGHTERED in Nanking by the Imperial Japanese?!
“The Sun Shall NEVER SET Over the Japanese Empire.” ~ Imperial Japanese Mantra
That means over 🫵🏻 head too, Budroe!
There wasn’t a single Japanese citizen who didn’t blindly support and condone the bloody atrocities committed under their regime. You do realize that it took (2) atomic bombs to force them to capitulate?!
So true...
Trueman never apologized for his deeds...
It's true jao soldiers were their enemies,but what was the fault of innocent kids women and civilians. To quickly end the war and to survive the US soldiers who gave him the authority to kill millions of innocent people!!
how terrifying is it that one second you're living your day by day, walking to work, and the next you're literally ash
How terrifying is it that one second you are eating breakfast in the gallery on a battleship in your home port in a time of peace and the next you are burning to death because of a japanese sneak attack on Pearl Harbor.
@@davidgenie-ci5zl dude extremely. i would not want to be anyone who got caught in anything on any side
@@KairysaWoW one act stopped the other, one act was necessary and right, the other act was pure evil.
@@davidgenie-ci5zltwo wrongs dont make it right or righteous bro
Yes. There were many horrors in this and other wars and in no way am I supporting the actions of Japanese during the war. But the power and complete lack of any warning make these bombs particularly scary. What is much more scary is how many much more powerful fusion bombs there are right now waiting to be unleashed.
Fireball and mushroom cloud rising at 13:23 in this video and thereafter are from the Nagasaki explosion, not Hiroshima. Footage of actual Hiroshima cloud rising can be seen here on UA-cam by searching "Harold Agnew Atomic Bomb Film," from 1:10- 1:40 (late cloud) and early cloud rising from 2:36- 3:01..... in case anyone wants to see the real thing. It's rarely used in documentaries because it's very grainy, shaky and is damaged somewhat.
This video was great, because although I've watched several documentaries on the bombing including the very recent Oppenheimer movie. I've never heard any information from the Japanese side of the story until this video, Thank you! The Japanese Emperor and his cabinet of men who played their part in the story was very enlightening to me. 😁👏
Shit america got away with murdering 350k+ civilians, while refusing to recognize the ICC for their war crimes, while pointing out the war crimes of other countries. The hypocrisy is nauseating.
Same here!
It sounds a lot more nuanced than "The Japanese refused to surrender, so we had to carry out the threat." that I was bought up to believe in the UK.
Shit america didn't need to use the bombs and many people have spoken about that. They murdered over 350k civilians and Truman was a lying pos..and, since america refuses to acknowledge the ICC, they have never been held accountable for many of the atrocities and war crimes they have committed.
@@pompeymonkey3271 Same here in Australia. It is always taught that the US had no choice but to use the nuclear weapons to stop Japanese and it just isn't the case. 98% of people wouldn't even know the Soviets role and invasion of Manchuria
Whose to blames. From president n alls military they r. D making war
Excellent video and a timely reminder of the terrible consequences of using nuclear weapons at this time of heightened risk in Europe. Accurate details and context, helpful in both this and the second video. Thank you for posting this.
Excellent work. Where is Part II??
It's only been 5 days since the upload chill
Logical question, no need to chill. If you don't know, that's fine

Im with you. Where is part 2? 🤣
Informative documentary. Been to Hiroshima twice. May all these souls who lost their lives that day and in the aftermath forever rest in peace
Been there once. Very erie and unreal to know what happened there. But visually looks like a normal functioning city now.
Casualties of a war no one wanted, the Japanese paid dearly for their barbarism
Maybe?? Just MAYBE? They should gave THOUGHT Bout it BEFORE Things like Pearl Harbour? The Bataan Death March? KobannTwon?? Just Sayin...God Bless. 😢
Barbarism? Read up on the events that led to Japan's "barbarism". @@nomaambundy9989
watch the video "no, we didnt have to nuke japan"
This video was very informative. I was lucky enough to visit Hiroshima recently and its a very chilling reminder of what happened there. The city is now very beautiful and welcoming but more importantly explained the importance of dangers using these weapons and the steps they took to recovery.
Part 1?!
You're killing me! 😵
Nothing draws my fascination as much as the MADness of nuclear weapons. I have watched a dozen videos about how exactly nuclear devastation functions and which destructive forces are at play and yet the utter scale of these things escapes my brain. Just the idea of deleting 100.000 thousand lives in an instant or that of a flash of light so intense that it turns a human being into a shadow burnt into the pavement is utter insanity.
But the most chilling thing about them is the fact that there is no in between. In the nuclear equillibrium, ensured by submarines, it is either atomic armageddon or not using them at all. And there are still people trying to reason themselfs into concepts like tactical use of nukes.
The worst thing about these weapons is the fact that our species cannot be trusted with them. Just research the name Vasili Arkhipov, he is the reason why we still have a civilisation. Yes, we actually were one decision from one man away from nuclear war.
I hope you guys make a video about him and other "near-annihilations-of-our-species-by-nukes" too.
Bros yappin
Compare that to the estimated 7 million Chinese civilians killed by the Japanese in WWII. Not to mention the hundreds of thousands of Filipino civilians killed by the Japanese. The Japanese killed a hell of a lot more people than the two nuclear bombs did.
I highly recommend visiting the peace park and museum in Hiroshima. It's incredible and extremely thought provoking. Hiroshima is a wonderful city and the people are very friendly. It's heartbreaking to know about this awful time in their past
Thanks Andy ✌
3:54 nobody gonna talk about the face in the smoke?
excellent video and very detailed.
Some things should have never been invented! Remember pain doesn’t die….it is just passed and builds up! 😖🙏🏻
The movie Oppenheimer, masterpiece.
My Father was saved by these bombs, he was to be in third wave on Honshu until this stopped it. I think Japan would have ceased to exist in the end. He was at Hiroshima weeks after the attack, he was not impressed; its beyond me but he was in Europe earlier
Tough shit for the people in Nagasaki and Hiroshima, eh?
@@gordonbgraham Just as tough shit as eating breakfast on the USN Arizona Sunday, Dec. 7th, 1941.
@@davidgenie-ci5zl Those were military...who were fair game in war. Why tf is Hawaii America anyway? And what was their naval fleet doing there? The Japaneses never hit any civilian targets on that raid. Not like the dozens of civilian cities the Americans firebombed.
@@davidgenie-ci5zl Military target...not an entire civilian population. HUGE difference
@@gordonbgraham It was not the entire civilian population that the bomb was dropped on. Furthermore those cities targeted housed military bases, weapons manufacturing. We also know that japan encouraged civilians to fight any invasion force. Hiroshima and nagasaki were both valid military target, and we were at war with japan. The bombing of Pearl Harbor was a barbaric vile sneak attack launched during peace time. Civilians too were killed at Pearl Harbor.
War is terrible 😢
Japan didnt think so back then.
Amen brother, my Dad was an Army guy trained to fight although he was a Heavy Duty mechanic.
In the 1980s, the BBC made a six part series about these devices. Search it out. Ever since the Japanese have placed themselves as victims of WWII when, in actual fact, they started the war in the Pacific and Asia.
Is it me or at 13:36 there is a face within the smoke of the mushroom cloud? Creepy, didn't it say something about necessary evil as a mission tag or something?
Exactly 😢
If you stop the video at 3:55, the trinity test explosion actually made a face of death - No wonder Oppenheimer ended up mentioning - "Now I am become death "
where? i see no face
@@AspieTrips I had a screenshot, but can't paste it here. So, slow the video down to .25x and pause exactly at 4:12, when the face is at it's peak contrast.
@@csajal Omg I just saw it lol, that was creepy!
I see a j3w
Oppenheimer was a whiner
Genuinely, the first time I watched the details of language issues and culture differences that added to the mistakes at the end of WW2
The big mistake was the japs bombing Pearl Harbor.
2018 i had a great holiday in Japan a 12 day break, & was well organized, i decided to add an extra 2 days to visit Hiroshima where the bomb was dropped. I stood in front of the monument for a few minutes it was so surreal. Then went into the museum for around an hour & you could see some of the haunting photos of the past & in the museum you had a special it was like a huge table & the table was covered in a huge round glass & in the middle of the table, was a sort of round balls depicting a number of bombs that were dropped. It was so haunting & walking around you had to remain so quiet & you could also sign a document as well
Wow go figure, a 17 minute part 1 video about the bombs >>> 3 hour movie of old men talking most of the time. Great video!
No more war please 😢
There will alway be war there’s nothing you can do about it war is just something that happens it’s out of our control unfortunately.
Many interesting factual details, good documentary. Where is part 2?
Part 2 is on UA-cam. Just use search box.
Read the book The Last Train from Hiroshima. The Little Boy bomb was only 1/3 the power of Fat Man. The author called it a DUD. The survivor stories are chilling.
Little Boy: 15 kt
Fat Man: 21 kt
As for survivor stories, read those who survived Unit 731.
This might have made the Japanese Empire surrender, but killing that many innocent people is a crime.
Dropping a nuclear weapon or even just threatening to use one, should be considered as a crime against humanity. Its a weapon of disgrace! An absolute disgusting weapon.
ah nope. You are applying a false morality. Compare the dead to the million allied soldiers and north of 10 million Japanese civilians that would have died in Operation Downfall. Compare the dead to the 100,000+ civilians dying each month in the Japanese occupied lands (mostly China).
What would you have done?
Tell that to Korea. Most of the people killed by the bombs were Korean slaves. Maybe if Korea had nukes so many of them would have not been enslaved. Their babies wouldn’t have been tossed in the air and sliced into by Japanese swords…
Innocent?
@@MrTexasDan That's a false alternative.
@@seanwebb605 Feel free to detail your claim.
@13:20 widely unknown fact, but this is actually footage of the bomb that was dropped on Nagasaki, not Hiroshima.
Where do you get high quality images for your thumbnail? How to make thumbnails like Science Time?
I worked at the Nuclear Refinery plant in Canada that supplied the uranium to this project
2:34 little boy ain’t so little💀💀💀
Silly question maybe, i havnt looked too hard into the rational of the two target citys. Im wondering why Tokyo wasn't the target? Any knowledge or thoughts on that?
8:40
Tokyo houses the Emperor - it was purposely saved for him to make decisions after the bombings as mentioned in this video.
They Reaped the Wind We Reaped The Whirlwind ! !
“extremely unlikely” ? I would have wanted to hear “‘impossible” first…..
How scary and terrifying,the cinematics were so dramatic and showed what could happen,let’s keep diplomacy forever on the table,nuclear war there is no winner but we all lose 🙏🙏🙏
Oppenheimer looks more like John Hurt than Cilian Murphy.
Where can I find part 2???
Wait for it to be released by this channel? 😂
@@TitaniumTurbine
Ya know.... that's a hell of an idea.
I think I shall wait
So who bombed Hiroshima and Nagasaki?
Do Japanese people know the nation that really did that ?
Does the very nation that did this realize that they are worse than the devil?
How hypocritical are they ?
The about 12 million dead all over SE Asia due to Japanese aggression want a word with you.
Look up Unit 731, Comfort Women, and Nanjing Massacre. Thats not even the half of it.
the manhattan project are the guys that created the bulletin of atomic scientists
Big egos and bigger fear. History is on an infinite loop of repetition.
I just wonder what would have happened to the world if the nuclear bomb would have been created several years later.
Or just a year or 2 earlier
Truman was never brought to justice over this genocide of innocent woman and children.
Wait till you hear what the Japanese did
@@emperorpalpatine7557 everyone likes to forget pearl harbor like it was no big deal
Please educate yourself on what war means …..
Who is the narrator here ??
Good question,I’m guessing a bbc person
I’ve never been okay with the idea of acceptable loss. I was not there and I get the gravity of the situation as a whole but that’s just too many innocent women and children
@@peter_d
Innocent women and children?
And what about the 32,000 Japanese troops stationed at Hiroshima? Were they innocent?
What about the fact that a lot of those women, and their husbands who weren't soldiers, worked at the 17 major war material production plants in Hiroshima?
What about the millions of women and children who died horribly from the actions of the Japanese in China, Philippines, Indochina, Malaysia, Indonesia, and Burma? They weren't innocent because they didn't get nuked by Americans?
You anti American whiners never want any of this to be mentioned, do you? Or is just that you are commenting on something that you really don't know about?
400,000 US troops killed, camp 317 1937-1945 14,000 were killed. (There own countrymen. Absolutely disgusting. Human experiments. Pearl harbor 2,403 sailors died. Yes WW2 was awful. At the same time the bombs ended the pain.
would you be saying that if they bombed the US 🤔
You keep convincing yourself of that
Ended the pain? go see the after effects of the hiroshima bombing
my dad walked there month after bomb dropped in clean up guns duty.
On Netflix there is or was a documentary named Black Rain. It is heart breaking.
Yes...very 😔
And no one knows we might have built The Cobalt.... why would they tell anyone...
13:37 Pause. I’m sorry but I can’t help it. Do you see its face?
I see this 🗿
It didn't happen that long ago which is also scary. It's like Japan just forgot about it.
How many people at Pearl Harbor died vs the retribution that followed? 😮
I hope this would not happen to New York! That would be horrible! ☮️🦄🐍

LMAO WHAT!
DON'T MESS WITH US 🇺🇲⚡🇺🇲
Kind of sickening how they chose civilians over the generals and emperors leading the army
The Japanese murdered 30 million civilians while "liberating" what it called the Greater East Asia Co-Prosperity Sphere from colonial rule. About 23 million of these were ethnic Chinese. It is a crime that in sheer numbers is far greater than the Nazi Holocaust.
This must NEVER happen again. It should NOT of happened in the 1st place anyway thousands of innocent folk lost their life's.
The sun's core is a wee bit hotter than 1,800,000 °F (as stated at 12:18). It's more like 27 million degrees F.
That's why most only go there in the winter.

So 12-7-41 was a mistake ?
@11:50 it took 44.4 seconds to descend to detonation…in Asian culture the #4 is looked at as bad luck…our number 13…that’s weird….
pause at 3.56 trumans face in cloud
I never knew that Japan started this war, I was always blaming America
Just to be clear, the Japanese massacred as many people in nanking as died in both bombings combined, and that is just one city…. They were NOT going to give up……
I feel like every general in Japan shared a name with a car manufacturer 😅
true
106k civilians instantly dead😳😩 Japanese thought it was a game

That is NOT funny.
For all those screaming we didn't need to use the bomb to get Japan to surrender. For the USA to take 2 islands in the Pacific cost us 85k killed or wounded men and 365 ships damaged or sunk.
The War Department after the battle of Suri Ridge on Okinawa redid the estimated cost in human lives for the invasion of mainland Japan. They placed an order for 1 million purple heart medals. After Japan surrendered on August 15th that order was canceled but hundreds of thousands had been delivered already. Those already delivered medals saw the USA through all armed conflicts through the end of the 20th century. We didn't have to order more until the war on terror.
Nonsense.
@seanwebb605 those were the combined KIA WIA and MIA of the Okinawa and Iwo Jima landings. Why are there people listed as MIA when you're on a plane that gets shot down or in a compartment of a ship that get hit by a kamikaze and then afterwards they can't find you.

May the Japanese people someday admit what they did to tens of millions (yes, that's correct; look it up) of innocent civilians in China, Philippines, Indochina, Malaysia, Indonesia, and Burma. They started the war long before Pearl Harbor, 8 years before they reaped what they sowed.
They've still got a lot of begging for forgiveness themselves before they earn the right to grant forgiveness to anyone else.

That's a pretty good way to say terrorist attack
The words never again are just words that are said by the U.S. government and the people of the world .
Yet there will always be the first and second time that came before the words never again were ever said or spoken .
The words never surrender were said spoken and believed , and that understanding unleashed the second of the last that came before the words never again .
The United States of America has never been faced with the decision to surrender to Victor . The Japanese people refused to surrender, and that decision and the consequences of not saying surrender resulted in receiving the second after the first with threats of three and four until the words we surrender were said and spoken . Will the United States of America ever face the same decision or will the entire planet called earth be totally destroyed before the United States of America , says the words we surrender .
