- Skepticism about Russia’s Nuclear Arsenal
- 0:00
- One of the underlying themes of the War in Ukraine is U.S. reticence to fully commit
- to the fight due to Russian nuclear weapons. Certainly we have spent a bunch of time on it.
- Heck, this one on nukes failing to deter was from just a few weeks ago.
- But one thing we have not yet discussed is a more basic question:
- will the silly things even work?
- Many of you have your doubts, but you lean toward them mostly being okay.
- So, today, let’s try to figure it out.
- We will start with the basic problems that all countries have with nuclear maintenance
- and then analyze and critique three reasons why Russia might be struggling with the upkeep:
- first, the literal inability to handle the problem,
- second, corruption and graft within the Russian military ranks,
- and finally a more general strategic reason why
- you might intentionally let your nuclear weapons decay.
- Oh, and you will definitely want to stay until the
- 1:02
- end because that one is a literal textbook lines on maps problem.
- Basic Nuclear Weapons Maintenance
- But we start with the basic need for nuclear weapons maintenance.
- You might recall from that most recent foray on the subject that
- Russia is the largest nuclear weapons power at just under 5600 total bombs.
- About 1700 of them are supposed to be ready to go,
- 2700 are in storage and could be made ready in short order,
- and 1200 are being phased out but could potentially be brought back into the fold.
- You may also recall that Russia’s arsenal is split into both the big
- strategic bombs meant to destroy cities, and about a thousand are tactical nuclear
- weapons that tend to be smaller and are meant for battlefield use.
- However, the problem for any nuclear weapons state
- is that you cannot just build them once and expect them to last for decades.
- 2:00
- You see, nuclear weapons are very precise devices,
- with thousands of components. A vast majority of them are critical to the explosive process.
- If a single one of those malfunctions, you will not get the big boom that you desire.
- For example, take the common implosion design.
- Here, you begin a core of weapons-grade plutonium. Thankfully, it does not immediately
- explode in its normal state. Someone help me bring it back. Thank you.
- Rather, for the chain reaction to begin,
- you need to make the core denser. Then you get the explosion.
- The basic idea is that you need neutrons to hit those fissile plutonium atoms,
- and that is easier when everything is closer together.
- The way a nuclear weapon
- does that is first by constructing a shell, and then lining it with conventional explosives
- all around the sphere, and all aimed inward. The plutonium pit then goes inside.
- When you are ready, the conventional explosions all
- 3:01
- go off at the exact same time, the pit condenses,
- and you get your mushroom cloud. The problem is that when I said
- the exact same time, I meant the exact same time.
- Going back to the diagram,
- if you are off by even just a bit, the pit flattens into a pancake.
- That increases surface area to volume, which has the opposite effect of what you want.
- Neutrons instead become more likely to escape into the universe,
- rather than hit that sweet, sweet plutonium.
- Moreover, this is a particularly weak point for Russia. Many suspect
- that the Russian manufacturing process struggles with the creation of the pit.
- The issue, in theory, does not doom the entire system. Rather,
- the pits need to be replaced every ten to fifteen years.
- That would mean, at minimum, every nuclear weapon in Russia’s arsenal should have
- 4:00
- gone through two if not three refurbishing processes since the fall of the Soviet Union.
- But it gets more complicated. If you want an efficient nuclear weapon,
- you have to add another layer to this by putting a pit of hydrogen inside the plutonium.
- Now, that hydrogen is actually a mixture of deuterium and tritium.
- Deuterium is the hydrogen isotope with two nucleons in its nucleus,
- hence the prefix “deu”.
- Tritium, meanwhile, is the isotope with three nucleons,
- hence the prefix “tri”.
- Both also have one electron.
- Ordinarily, deuterium and tritium do not like each other much.
- But expose them to immense heat—say, that of a nuclear blast—
- and suddenly they want to become best friends.
- In doing so, they combine together to form helium.
- This specific form of helium has two protons,
- two neutrons, and two electrons.
- If we check our math real quick, we will see that, yep,
- 5:02
- there is an excess neutron left over here, all by itself.
- Why does this matter?
- Well, going back to our regular bomb,
- recall that the chain reaction happens because the condensed pit increases the chances that
- a neutron hits an atom of plutonium and thereby causes further fission.
- The deuterium-tritium reaction saves a step by just unleashing
- massive numbers of neutrons directly into the target area.
- That increases the efficiency of the weapon,
- allowing you to miniaturize the design while still producing the desired yield.
- The complication here is that tritium has a half-life of about 12.5 years.
- As a result, you may need to cycle out your tritium every
- five to ten to keep the bombs working properly.
- That would mean that Russia would be on its third rotation there at minimum.
- Is Russia Incapable of Maintaining Nuclear Weapons?
- Okay, so that is the problem in broad strokes. Let’s switch to looking
- at reasons that Russia’s nuclear arsenal may no longer work, beginning with inability.
- 6:06
- This concern could be subdivided into financial and technical limitations.
- On the financial side,
- there is a perception that the primary cost of nuclear weapons is in the development cycle.
- However, that is inaccurate. Focusing on the United States,
- because we do not exactly have reliable estimates for Russia,
- the Manhattan Project cost $51 billion.
- But through 1996, the United States had spent $821 billion on keeping its bombs functional.
- Part of this is the expansion of its arsenal—keep in mind that the United States once possessed
- an absurdly large number of nuclear weapons.
- But much of it also went to ensuring that what it had
- actually worked properly. To get a taste of how the numbers can run up so quickly,
- tritium costs about
- $30,000 per gram.
- 7:02
- By comparison, that is about the weight of a paperclip.
- Now, an average weapon might require a little more three grams of tritium.
- So at least every ten years, Russia needs to spend about
- $100,000 per tritium boosted nuclear weapon, and just for the tritium.
- Remember, though, nuclear weapons have thousands of parts,
- as do the systems that they are connected to. And while graciously
- tritium is more expensive to maintain than the vast majority of them,
- you can see how this adds up.
- That was the financial part. The other half is sheer ability.
- Concerns here usually stem from the breakdown of Russia’s education
- system after the Soviet Union dissolved. Think about the 30 year olds at the time.
- They are final cohort of Soviets who received advanced degrees. Well,
- they are now in their 60s, meaning that they are hitting retirement age.
- 8:01
- Oh, and as if to further troll the Kremlin, their retirement is also
- exacerbating the financial problem by squeezing the Russian pension program.
- But returning to capacity, if you think that the knowledge of that cohort has
- not been passed down to others, then Russia’s program might be in trouble.
- It does not help that Russia has never tested a nuclear weapon.
- The last Russia-affiliated test occurred in 1990,
- still under the Soviet banner.
- And, as a gentle reminder, poorly-monitored AI is still dumb: the largest Soviet test did not
- occur on October 24, 1990. It occurred in 1961, and that is an abundantly easy fact to check.
- I am not sure if this silly picture makes up for that.
- Why Russia Is Probably Capable
- In any case, there are many reasons to think that
- capacity is not an issue. Let’s stick with the pure ability part for a second.
- In the absence of a proper nuclear weapons test,
- 9:02
- we can gauge nuclear science ability in the country more generally
- with power plant operation.
- Russia has a ton of them, and they still work just
- fine. A lot of them may be on the end of their life cycles,
- and some of them are nearby invading Ukrainian soldiers,
- but if we are worried about what is happening right now, knowledge does not seem to be an issue.
- Even the more technical parts are not an obvious problem.
- Russia appears to still have a nuclear reactor capable of producing tritium.
- And even if it did not, the Soviet Union bequeathed Russia 30,000 bombs.
- You see, tritium has gone through about three half life cycles since then,
- and it is possible to remove tritium from the weapons,
- purify it so all of the half life junk is gone, and insert the tritium back into a weapon.
- Well, take 30,000 divide it by 2,
- divide that by 2,
- and divide that by 2 and the result is 3750.
- 10:03
- Thus, what is leftover is enough to fuel a majority of Russia’s current weapons.
- Now, those are rough calculations, not accounting for the types of
- weapons. The fact is, I do not have perfect intelligence of what is happening there.
- The point is, though, that there is still plenty of tritium to be
- had in Russia. Is there a loss of institutional knowledge? Sure.
- But that is true for everyone—for example,
- American officers are unlikely to be familiar with these kinds of fallout timetables.
- And keep in mind that tritium is not necessary for a weapon.
- It just boosts the outcome of an already-exploding bomb.
- So, even if the tritium is all gone, that does not fully solve the problem.
- Okay, that is the ability part. What about the finances?
- Well, corners certainly had to be cut on the federal budget, especially during
- the transition period and before the surge in energy exports that Russia would later enjoy.
- 11:03
- But during that period, Russia prioritized its nuclear weapons arsenal. So, if anything,
- it was in good shape compared to the rest of the armed forces.
- Moreover, hundreds of millions of dollars in upkeep sounds like a lot of money,
- but it is manageable for a large country’s budget.
- However, that assumes that all of the money intended for the program
- actually goes into the program— because, to the average person,
- hundreds of millions sounds like quite a lot.
- Corruption
- And that takes us to the second concern: corruption. This is a more serious problem.
- In fact, the reason the war began and continues at all is in part due to corruption.
- The Kremlin believed that the invasion would be easy,
- and that Russian forces would quickly overpower an outmatched Ukrainian army.
- Kyiv was skeptical, on the other hand, especially regarding the status of Russian forces.
- 12:03
- That led to the Kremlin’s initial miscalculation that drove the war.
- Then Russia got bogged down during its invasion of Kyiv. It turns out that selling
- your vehicle’s protective armor plating as scrap metal is not conducive to survival.
- Nor is siphoning the petrol in your vehicle to sell on the black market
- conducive to arriving on time at the capital.
- Hence Kyiv survived.
- If that type of corruption filtered up to the nuclear level,
- Russia may be unable to atomically escalate even if it wanted to.
- A connected problem is with Russia’s delivery systems. Nuclear weapons
- that can go boom still are not helpful if they never arrive on the opponent’s soil.
- The beginning of the war also raised an issue here.
- The DoD indicated that Russia’s various missile systems
- experienced a 20 to 60 percent failure rate.
- Similar numbers would not be reassuring when the payload is radioactive.
- Why the West Should Not Bank on Corruption
- 13:03
- Again, though, this possibility should not put anyone in the West at ease.
- You see, nuclear weapons are not subject to the
- same corruption issues as the rest of the Russian military.
- As a starting point, those corruption issues became evident to the Kremlin
- more than two years ago. Although Russia has not fixed them all,
- the government has taken steps to improve the situation.
- But let’s imagine that the Kremlin has not applied any
- of those extra precautions to the nuclear field.
- Well, one of the reasons that autocrats find nuclear weapons attractive in
- the first place is that the process is concentrated into relatively few hands.
- For a comparison, think about how difficult it is
- to confirm that your army is ready to launch an offensive.
- To do a thorough job, you have to check tens of thousands of
- pieces of equipment one-by-one. You cannot just examine a single vehicle
- 14:00
- and expect that to get you anywhere with your military plans. And even
- if you audit a ton of them, you must still worry
- that your lieutenants are not showing you a representative sample.
- Their title even warns you of the problem. But this auditing issue
- is not a problem for a one-off nuclear explosion.
- If you are confident that the bomb will do its job, then that is the end of it. So,
- yes, corruption may still happen along the nuclear supply chain.
- But catching it is easier. And certainly when you are at the point where you want to fire
- the silly thing, you can double check all its vital components.
- Put another way, you cannot naively apply that
- 20 to 60 percent missile failure rate from earlier to nuclear weapons.
- You see, there is not much concern for any country, Russia or otherwise,
- about whether a single conventional missile fails.
- Each one is expensive, yes, but it is not a national scandal if it blows up early.
- 15:03
- However, the same cannot be said when the payload is nuclear.
- Also, that 20 to 60 percent failure rate included missiles that missed their targets.
- But as the saying goes, close only counts in horseshoes,
- hand grenades, and nuclear weapons.
- In any case, let’s suppose that the corruption is extremely bad,
- and only a fifth of Russia’s nuclear weapons work.
- Well, what do you call it when a nuclear weapon explodes over Berlin?
- Answer: a bad day.
- What do you call it when a nuclear weapon explodes over Rome but four
- fail to ignite? I do not know about you, but I would still call that
- a bad day.
- I also cannot speak for historians,
- but I suspect that second part would go down as a footnote in the textbooks,
- and readers skip those anyway.
- To draw an analogy, it would be like playing Russian roulette,
- which is something that anyone with three grams of self-preservation tries to avoid. Heck,
- 16:04
- even if 90% of Russia’s 5580 nuclear weapons do not work,
- what is left is still larger than China’s entire arsenal.
- But exiting the casino for a second,
- that is actually one of the reasons why both Russia and the United States
- keep their stockpiles so large: redundancy is an insurance policy.
- The upshot for the West is that an attempt to wipe out the entire U.S. arsenal in a
- first strike does require accuracy and confidence that each nuke will work,
- but that is not the concern at the moment…
- Strategic Decay
- 16:40
- Finally, let’s talk about strategic decay.
- Strangely, it is a perfectly reasonable decision
- to not keep your nuclear weapons in good condition.
- The problem here is verifiability. It is hard to
- know whether your opponent has maintained its arsenal or not.
- And that in turn gives rise to bluffing behaviors, the calling of perceived bluffs,
- 17:03
- and potentially war. And now the moment that we have all been waiting for:
- Let’s go to the lines on maps!
- Imagine a world where a nuclear power dutifully refreshed its weapons.
- Well, as any long-time viewer knows, when you try settling your political differences,
- negotiated agreements must be commensurate with the balance of military power.
- Nuclear weapons grant you some of that military power. And if everyone knows you that dutifully
- maintain your weapons, then they will not think
- of you as a weakling like this. Rather, they will recognize that
- military outcomes are more favorable to you, and so you can reap the benefits accordingly.
- But then one day one of your military advisors gets clever. He points out
- that everyone thinks that you maintain your arsenal. And due to a malfunction
- in my animation procedures, he is pulsating very angrily about it.
- The thing is, though, no one can actually verify that you maintain everything. It is just a belief.
- 18:04
- Further, because he watched the first half of this video,
- he also points out that maintaining the arsenal
- is very expensive. So he recommends that you just stop paying for the upkeep.
- And that suggestion could not come at a better time:
- your conventional military in Ukraine is draining your budget anyway.
- You don’t tell anyone about the cutbacks, of course, and so you get the best of both worlds:
- coercive leverage predicated on you having nuclear weapons
- but not having to pay a dime to do it.
- Of course, a clever advisor on the opposite side might point out that
- the nuclear power would have this exact incentive to bluff,
- and therefore they should not be sure whether they are facing
- a fully-functional nuclear adversary or not.
- It’s a puzzle…
- Well, fortunately, the lines on maps professionals have worked through this scenario.
- 19:01
- Sure enough, the nuclear state sometimes should lean toward the bluff—but it ought
- not assuredly do so, otherwise everyone would know that it is a paper tiger.
- Meanwhile, the opposing state must sometimes call what it thinks might be a bluff by holding firm
- on its demands, and treating the opponent like it does not have nuclear weapons.
- This has the unfortunate effect of leading to conflict when the
- nuclear state did properly maintain its arsenal.
- Yikes!
- And less reassuringly, the probability of war increases as the cost of maintenance increases.
- The logic here is that the more costly it is to not cheat the system,
- the more tempting it is to bluff,
- and thus the opposing state has to be more proactive in calling those possible bluffs.
- On the bright side,
- extremely high costs eventually invalidate the problem.
- Indeed, when the costs exceed the value of the additional military strength,
- then everyone knows that the nuclear power would abandon the program entirely at that point.
- 20:04
- Let me clarify this logic with some lines.
- Visually, even if maintaining the arsenal extends your power out to here,
- you would not do it if the cost effectively pushed back this far.
- In turn, the opponent can infer that the weapons program has been abandoned,
- and adjust its offer to avoid war accordingly.
- That is, everyone understands that the power distribution is here,
- and so the settlement occurs somewhere around there.
- But even in the case where conflict does break out,
- that does not mean that we will inherently jump to a nuclear war.
- It might just force Russia’s hand into testing some nuclear
- weapons to eliminate Washington’s doubts.
- In any case, the observable U.S. reticence tells us something here. Its intel analysts—who
- have more to go from than us Internet warriors—believe that Russia is capable,
- or, alternatively, that the underlying preferences in the White House are extremely risk adverse.
- 21:04
- But whatever is the driver, at least for the moment,
- we are not yet walking down a path of nuclear annihilation.
- Meanwhile, if you are worried about nuclear annihilation,
- might I suggest the paperback copies of my books on the war? They will
- resist electromagnetic pulses much better than
- the Ebola will. You know what, autocorrect refuses to acknowledge
- that “ebooks” is a word, so I am just going to go with it.
- Ebola!
