The Atomic Bomb: Crash Course History of Science #33

The story picks up where we left off last time, with Einstein writing the president of his new homeland, the United States, urging him to build a nuclear weapon before Hitler. This is the tale of the most destructive force humans have ever unleashed. The Atomic Bomb.

Yeah... history (and really, really simple game theory) very clearly show that showing off a super weapon to your enemies does *not* carry the message “you should fear us.” Almost always the received message is “you should get some of these as quickly as possible.”

And should also help your enemy get one ASAP. Whole point of M.A.D to have both sides weapons so powerful that open conflict is out of questions and you can get back to normal peaceful lives (no point in waging war anyway)

Though Truman didn't know this at the time. Stalin knew far more about the Atomic bomb even at Potsdam that Truman ever did. I'm not exactly sure that the two statements are mutually exclusive though. 'It's fear us while we have this superiority, try to acquire it asap to level, and then escalate, the field.' Which looking at extant declassified records from the CCCP is pretty much how it was actually taken.

Considering the Japanese military high command still did not want to surrender after the atomic bombings, and there was an attempted coup against Hirohito when he announced he was going to force Japan to surrender, and there is strong evidence to suggest Operation Downfall was not only going to fail, but make Iwo Jima and Okinawa look like child's play in terms of intensity and casualty loss, it's hard to argue US success was still certain. Japanese strategy had shifted towards keeping allied forces off the island and waiting until their resolve had diminished, as they had done in the past with groups like the Mongols. The High command was willing to sacrifice everyone in Japan to this goal.

[@badbeardbill9956]

RomanianJ96 No Japan couldn’t win. We’d just blockade them and starve them out.

[@RomanianJ96]

Bad Beard Bill We already were blockading them and they still weren’t giving up. All of Japan was starving and the high command had decided they didn’t care how many Japanese died or how long it took. As long as the Allies never successfully invaded the home islands they felt they could just wait out the Allies.

[@badbeardbill9956]

@@RomanianJ96Except they couldn't. They needed the resources of other lands, otherwise they wouldn't have even built their empire. They relied on those resources. Their people were starving. Eventually they all would've died, leaving a dead island chain.

[@RomanianJ96]

Bad Beard Bill And the Japanese high command were willing to pay that price. I’m not arguing over whether they would have won World War 2, that was impossible even after Pearl Harbor. I’m arguing about their resolve. If Hirohito hadn’t strong armed the military high command into capitulating, we would see Operation Downfall happen, which MacArthur wanted to use nukes to soften up the beaches. These landings would’ve most likely failed since it was a 1:1 ratio when the Japanese surrendered between invader and defender, and the Japanese were not even done fortifying Kyushu. The blockade would’ve taken years and Truman was worried about the American public losing interest in carrying out this expensive war. Plus, he was worried about letting the Soviets expand their influence into East Asia just as they had done in Europe. There were no good or easy decisions to be made. Starving out an entire country is a hard and bloody task to achieve. Especially when you’re starving out a people who are willing to suffer whatever it takes to force you to end the war somewhat favorable to them.

[@badbeardbill9956]

@@RomanianJ96The high command may be willing to fight but they don't matter. The people do. If they refuse (and they likely would eventually) then it doesn't matter if the leaders are willing to pay that price. What matters is whether or not the people are. Sure, some wouldn't. But many would. And even if they don't refuse the Japanese Empire had enormous trouble just feeding their soldiers. Feeding their people would be even more difficult and their entire population would be effectively useless as combatants.

I love Crash Course but I have to agree with a lot of the commentors about the one-sidedness of this particular episode. I'm not qualified to have an opinion as to whether the bombing of Japan in WW2 actually saved lives by shortening the land-war. However, just listing nuclear incidents of the 20th century without mentioning the advantages and widespread stability of nuclear power in general was a very slanted view of a complex subject.

[@snkline]

This sorta reminded me of the original SciShow GMO episode. GMOs, Nuclear Power, and Anti-Vax seem to be the three big anti-science boogeymen that are quite popular in liberal circles (that doesn't mean they aren't popular in conservative circles as well). While he hasn't fallen for the anti-vax nonsense, he did fall for the anti-GMO nonsense until his video gave him a rude awakening, and this video reveals at least a slight anti-nuclear bias as well.

[@Jaydoggy531]

7:52 "And now there's an opera about him" - it's called Doctor Atomic by John Adams. The whole script is compiled from journals, letters, and de-classified documents from the actual people involved. It's a bit fragmented and jagged, but then again... so is war.

[@bryanlandwehr7422]

The units of success to the cold war also included atomic bomb delivery capabilities (rockets). Bombs aren't a useful show of force, unless you can put them where you want to... Or at least convince the world that you can. This fact directly contributed to the space race and some of the more tense moments of the cold war like the Cuban missile crisis.

As a student of history, and especially of military history, the only reason there wasn't a third world war in the 20th century was the existence of nuclear weapons. It's a huge gamble, but so far nukes have prevented wars. How long this will be the case is another question.

Yeah, I was like “what?” I think it’s generally agreed that dropping the bomb, saved millions of lives, both American and Japanese.

[@fleebertreatise1063]

Do Historians agree? I found the Gar Alperovitz articles, but he's one guy and while his points may be sound, he doesn't represent "historians" as a whole. I found a good article here though (search Washington Post "How the Hiroshima Bombing is Taught"). It has links to public opinion (in the US and around the world), and how history textbooks are taking more evidence into consideration. Evidence like dissenting voices at the time of decision, and the effect it had on the victims. Personally I think that restricting how we talk about the bomb as a "necessary evil" is incredibly stupid. We need to take into consideration whether there were alternatives, and all the facts at the time. Not just the facts that preserve the belief that all our decisions were correct. If you have evidence that this is an open and shut case, I'd love to hear it.

[@Nostripe361]

Joseph Ramirez I think it’s a little of both. A bit cause it was better than invasion and a bit as a way to show it off to the Soviets. Basically there was no one reason but a multitude reasons they dropped the bomb

[@christophermiller1703]

@@Nostripe361 Yes, I agree. There are many factors which affected the creation and use of the atomic bomb. This is not so black and white as some like to portray it. Alperovitz is one of the foremost revisionists on this topic and it is good to have historians examining this event from all different points of view. But one voice does not a majority make. I generally like John Green and I find his Crash Course series informative and generally reliable. However, we have to be careful, as historians, not to speak in absolutes too easily. "Always" "most" "never".....these are hard to prove. And if you make these statements, you need to back them up with solid sources.

[@Nostripe361]

@@christophermiller1703 History is almost always a murky gray. Even the most evil men of history have done a few good things even if outweighed by the evil they have wrought. And likewise even greatest hero of the past has dark sins in their closest. Not to mention alot of it will always be inference based on what we have as evidence. However people and historians don't like that. They want easy answers that can be viewed as 100 percent true. Which is why you should look at all historical viewpoints

Yea. The invasion would've taken far more lives than the bombs did.

[@SaraBearRawr0312]

@@alexanderwasley5105 Possibly but that is also why it is still so hotly contested today. Japan as a nation was prepared to continue fighting to the bitter end but a nation is not an individual person and the war was already taking a toll on those very persons. By spring 1945 it was well understood that if the war continued, the Japanese would eventually see American boots on the Japanese mainland which in itself was terrifying but also terrifying was a united front of America and the USSR as they understood that while America might be somewhat civil (wartime atrocities not-withstanding) the soviets might not be so clean in their fighting. This was not only on the minds of the Japanese gov't but also on the minds of the soldiers and civilians who would have to endure the invasion, bombings, and ultimately street fighting. Would the Japanese just completely surrender once allied troops landed? Obviously not; but would a prolonged multi-year conflict with hundreds of thousands of US casualties and a million Japanese casualties occur like is publicly theorized? Most likely not. The Japanese resources were drained, their weapon stocks dwindling, their navy nearly entirely annihilated, and a sort of pseudo-blockade was already in place to prevent outside aide; and probably most telling, their morale was fading quickly and the will to fight of the everyday citizen was getting lower and lower. Another potential issue involved that very coalition. We already understood that the Soviet sphere of influence was going to increase with Germanys fall and not even a decade later we would see this with Korea, looking at it from today it would almost certainly end with a divided Japan with Soviet and US partitions just like Korea. This would have been a reason to get the US in as quickly as possible without allowing the soviets to get any footholds despite being an "ally". While there are other factors that were unique to Korea which ultimately culminated in the Korean War, notably the long standing issue of Korea (under Kim) wanting to stop the centuries long issue of constant invasion, it isn't hard to see an east/west germany or north/south korea issue developing in a divided occupied Japan. While we will never know the true extent of such a conflict, If it is from purely a casualty perspective as many like to point out here is my issue: its believed that had an invasion occurred, the Japanese would have sued for peace after only a few months due to those issues listed above and so the question still stands of the risk-cost analysis of the aftermath: Was 200,000 Japanese casualties, the vast majority of which were non-combatant citizens, lower or higher than a proper conflict involving soldiers? Is a soldier worth more or less than a civilian when calculating this? War is already complicated enough both during and in the retrospect but once we opened pandoras box of the nuclear option it changed the paradigm in such a way that Oppenheimers quotation is even more pressing: We, humanity, have "become death", and we will have to contend with that and question our decision for the rest of human history if we plan to not finish his quotation and become the "destroyer of worlds".

Yet even after the first and second bombs were dropped Japans government was refusing to surrender. It took the Emperor stepping in to end the war and even then the military tried to prevent Japan from surrendering thinking that someone was forcing the Emperor to surrender. Had the bombs not had been dropped Japan would have forced us and our allies to land hundreds of divisions on Japan causing way more casualties then the bombs caused to both sides. And in the mean time while the invasion of Japan was planned the US and allies would have continued to bomb Japan causing way more casualties there then the nukes did. And then there also would have been all the fighting happening on the land on the islands of the Pacific and the mainland of Asia. So not believing the US was justified in dropping the bombs to end the war is really ridiculous. If you disagree please let me know why you think that.

A whole episode on nuclear fission, and no mention of Lise Meitner? Crash Course, I am disappoint.

[@bobfearnley5724]

This is about the weapon of the nuclear bomb, not the energy production.

So what about the Tube Alloys project and the MAUD Committee?

Please do a video on missile defense.

Imagine if we put our efforts into perfecting fusion technology to exploring our Solar system (and later, Interstellar space), instead of pointing it at our fellow humans... One can dream.

Somebody set up us the bomb!

Preventing a long, drawn-out war was undeniably a factor in the decision. It may not have been the primary factor, but it still was a factor. You should have listed three factors in your graphic.

[@aboubacaramine8689]

Right because long drawn-out wars are so uncharacteristic of US foreign policy.

@@aboubacaramine8689 Check out the prager u vid. Lots more people would have died had a real invasion taken place. Doesnt adress your point directly.... but i thought that tidbit might help

Yeah man I’m annoyed that he didn’t establish how is rhe USA didn’t use the bomb and chose instead to invade we would have another D-Day but 10x worst! Storming Japan’s beaches would’ve been horrible and killed tones not to mention that we would’ve had to take the entire island which would killed civilians, and Soldiers. That bomb while horrific and horrible was in my opinion the better option out of the 2

I also think it’s funny he has no mention of the paper slips that the USA dropped warning Japan but whatever I guess :(
