"Which is why for the longest time we focused on hitting ICBMs while they were still on their way up or at the top of their arc. This test is specifically to prove out having the capability to also hit the ones remaining at the end."
Huh?
This history of *serious* missile defense in the US dates to the mid-1950s, so that's about 70 years of effort. During that time we only seriously considered boost-phase attacks during a single decade starting in the mid-1980s. One can consider the actual programs:
Wizard - terminal phase Nike Zeus - terminal phase Nike-X - terminal phase Sentinel - terminal phase Safeguard - terminal phase LoADS/Sentry - terminal (20,000 feet) Swarmjet - EXTREMELY terminal (5,000 feet!) SDI - boost phase THAAD - terminal/midcourse on theatre-range systems YAL-1 - boost phase, basically doesn't work PLV et al - terminal/midcourse on ICBMs
Doing boost-phase is hard and expensive even against low-quality single-missile threats. Terminal has its problems but is technically much easier.
That's enough warheads to drop 3 on the 30 largest cities in the US.
The system has no capability to shoot down this many. This is doubly true because anyone able to launch that many will also launch hundreds of high-quality decoys that the system is unable to distinguish (as opposed to low quality ones from other nations)
Because of the overkill on those targets, shooting down even the majority of them will have almost zero effect on the outcome. Dropping three warheads on Manhatten has basically the same effect as dropping two.
This is the sad mathematics of missile defence. But this was all widely studied in the 60s, google Prim-Read theory in Books.
"In the first test of its kind, the Pentagon on Monday carried out a "salvo" intercept of an unarmed missile soaring over the Pacific, using two interceptor missiles launched from underground silos in southern California."
"What if a combination of a reflective roof, improved sealing and insulation of attic ducts, and a higher-efficiency A/C unit is more cost effective than a solar photovoltaic panel?"
Then do that too.
I think you're missing the point that this is not a rooftop system. That's important. For argument's sake, let's say this system is 1GW peak. To deploy that on homes you'd need to install 200,000 average 5k rooftop systems. Or, as you suggest, you could improve existing systems to lower the energy use. If that's 1kW per home, then you need 1,000,000 homes to be upgraded.
Current pricing on utility-scale solar is about 80 cents/W. So installing one 1 GW plant will cost you about 800 million dollars. In contrast, installing on the rooftop costs about $3.25/W, so that option would be 3.25 billion dollars. Re-doing the homes as you suggest will cost thousands per home, so I would not be surprised if it was tens of billions.
So the end result is the same, 1GW offset. One solution costs many times less than the others. Done like dinner.

"This is why I personally think Level 2 autonomy is a bad idea," warns Jalopnik. "If it's possible for a moron like this to sleep while the car is driving at highway speeds, that's a huge problem."
Last spring a semi-trailer driver fell asleep on the 401 eastbound just up the road from my house (about 1.5 km away). As a result of some night-time construction, there was a traffic jam, and the truck piled into it at full speed and killed several people. The resulting accident study and cleanup left the entire highway, the business in North America or the world depending on who you ask, blocked for the majority of a day.
Level 2 autonomy should be legally mandated on all cars. If we can't stop people from falling asleep at the wheel, we should at least stop that from killing people.
Huh? "CN: Usage Price: Electricity for Industry: 35 kV & Above" from https://www.ceicdata.com/en/china/electricity-price
0.870 RMB/kWh = 13 cents USD/kWh
The US price for industrial power is lower across the board:
https://blsstrategies.com/docs/news/News_181.pdf
20 year solar PPAs are being signed for delivery this year at 1.4 cents/kWh. More realistic numbers for China are between 4 and 6 cents. That is precisely why China announced they were no longer offering any support on PV installs. Yet in spite of removing those incentives, current predictions are for ~45 GWp of installs this year in China alone.
It's not hard to see why: PV can be installed incrementally, one panel at a time. Therefore you can easily ramp up and down with supply-n-demand, labor availability, access to cash, etc. Wind and natural gas are next in line in scalability, the former ~1.5MW per install and the later around 200 kW in most cases. But for something like a reactor, it's 1 GW or nothing. This really skews the financing side toward the renewables.

> At GM quality suffered because "Instead of making flawless cars, workers simply did their assigned jobs,"
Uhhh, yeah, high quality like the ones coming out of the NUMI plant? Where the workers were often drunk on the job, and put their beer cans into the doors of the cars so there would be a rattle you couldn't fix?
I recall being in high school and watching a movie made many years before about working in a car plant. It involved a guy that had been working at the plant for many years and was now working on some machine where all he did was X all day long.
At one point a new worker asks for his advice working a spot welder because he knew the protagonist had worked it for many years, and our hero tells him there's a trick to it they don't teach you and shows him how to do it. Then the foreman arrives and tells the hero to piss off and shows the kid the Factor Way. The movie ended with a family being given a tour of the plant and the hero having a breakdown and yelling that all they cared about was the number of hands you had and that they should just pay you based on that.
The movie was apparently made in the 1950s or early 60s. There was very little "automation" in the modern sense, and zero robots, yet every problem being dumped on robots in this paper clearly existed in the same form and apparently even greater magnitude. Again, this is from about *60 to 70 years ago*, long before this paper begins.
He wrote this entire article about the Missile *Defense* Agency, and can't figure out the difference between a ballistic missile and an ANTI-ballistic missile.

Sure, and since then we used that data in ever-larger sky surveys and realized what we were seeing was the large scale structure of galactic layout with walls and voids. Since the majority of galaxies are found in certain structures, then of course one will find that their red shifts also tend to cluster.
Just look at your own list of papers, lots in the 60s and 70s, then less and less until the 2000s when its just a handful. Did the effect disappear, or did people just ascribe this to something more prosaic than the, well, whatever was supposed to be causing it?

I was at a construction trade show a few years back and came across a booth selling sound deadening pads that you just hung on your wall. The show, like all of them, was very noisy. I strongly recall standing so one ear was turned towards it and the other away. The effect was astonishing, it was MUCH quieter on the pad side. Oddly, however, it was that ear that began hurting after a short time. I think the brain does some sort of scaling and is trying hard to pull more sound out of the quiet side.
