On a positive note, maybe that shite stain from the video where he ran up and shot the guy in the car wreck wouldn't have been born.

There is still a nuke buried in the mud off the Carolina coast that was never found from that accident. The bomb that came close to arming would have not detonated with significant yield. Many of the components needed to initiate thermonuclear fusion were damaged in the accident. Worst case would have been a “fizzle” or very low level nuclear reaction, or a just the high explosives detonating scattering the nuclear material.
Solid work for a prowler puke

At least in a time of need the fickle ego maniac could read the codes in the absolute order as required to initiate “chopsticks”
By the 5th try it would take Lyin Biden to get it right the war would be over. Uhm or uh resets the protocol.

Trump was the most anti-war president we've had in a long time. In fact every time he tried to get us out of a conflict it was the left that pitched a fit and acted like grade schoolers

Are hydrogen (whatever they're called and how they were different) bombs still working by slamming two halves together?
I don't know where to begin with this.
A fission device is just that - a device that forces a (typically plutonium) weapon core to critical mass for fission (supercriticality) - either by the "gun style" (Little Boy) or the implosion style (Trinity, Fat Man, etc.).
A thermo-nuclear device is (again, typically) a 2-stage weapon that has a fission device as the first stage and then a second stage with thermonuclear fuel.
From a mental model both the "gun style" fission device and the Tellar-Ulam design (or the reverse engineered Soviet version of the same thing) involves a combination of weapon components, but neither can accurately be described as "slamming two halves together".

Before the government declassified some of the components of the bomb, a lot of encyclopedia (in particular my parents set of 1984 World Books) described the Hiroshima-style “Gun barrel” design as firing two pieces together.
Now we know it is really more like firing a hollow uranium cylinder towards a uranium plug, but the “slamming two halves together” concept is for all intents and purposes, a not entirely inaccurate oversimplification.

Fair enough, but I was responding to someone asking about "hydrogen" weapons as "slamming two halves together" and further qualified as "still", as if that had previously been the case. I agree with you that it was likely a misinterpretation of how the Little Boy uranium "bullet" design was commonly described in the past.
So, we can agree, that while 2-stage Ulam-Teller devices do combine weapon components, these main "hydrogen bomb" designs do not slam two halves together and never did, can we not?

Well, the Ulam-Teller design uses a plutonium implosion device as a trigger.
Off the top of my head, I don’t know why that trigger and not a gun barrel design. Be interested to know why that is used.

Which does not "slam two halves together". It crushes a core via implosion using conventional explosives in a concave shape.

Yield/efficiency primarily. The "gun barrel" was a uranium design, not very efficient and, I think could not be made small enough for deliverability (as part of a two-stage device). It was already obsolete, but it was already built. Another concern was it took a long time (relatively speaking) to detonate, relative to the implosion device. Being already built and was an essentially "fool proof" device, they didn't dismantle it.
That's why they tested the implosion device at Trinity over the Summer before the attacks. They knew the Little Boy design would work - it couldn't "not" work, absent a straight mechanical malfunction. The implosion device was a theory that hadn't been tested yet. In fact, as they continued to further develop the implosion devices, that led to the research that pointed them in the direction of the two-stage device.

One thing that always puzzled me when I was trying to learn about nuclear weapon design was the higher yield of thermonuclear devices. Again, I was relying on outdated speculation, but I was under the impression that somehow fusion produced more energy than fission.
But now I understand what is really going on is that, while fusion does produce energy itself, what really makes the thermonuclear design more powerful is that the when heavy hydrogen fuses to form helium, it loses masses in the form of high velocity neutrons, which are able to ignite a secondary fission fuel in the core of the fusion fuel. Fission here is 100s of times more efficient than in the initial fission trigger.

The scary thing is - selection of various materials (and, potentially a third stage) can make this 1000s and 1000s of times more efficient. Just no reason to, because a lot of smaller explosions end up being a more efficient weapon (system?) than 1 big bomb that wastes a lot of energy in one place.
There are theoretical limits to yield, particularly if you factor in deliverability, but it is beyond insanely high compared to weapons that have already been detonated.
