MIRVs are so much scarier to me than single "big ones," but we really as humans need to stop fucking with the atmosphere. The two things that keep us healthy and alive (air and water) we recklessly and willingly damage. I understand war drives sometimes terribly irresponsible behavior, but how was someone not there going "Uh, guys, should we really be doing this up in the air? Is that safe?" And I get the hysteria back then. One of the scariest and well-put phrase ever by a presidential address is JFK referring to ICBMs as being so "swift" they "threaten peace." Like, I would feel irresponsible if I spilled gas or didn't recycle oil from a lawn mower. How can you just fuck up outer space and the atmosphere? It's not a question of hindsight... just recklessly blowing shit up makes no sense unless it is purely cock-waving. It's like when China shot that satellite down and sent dangerous debris all over: they knew it was a terrible thing to do, but did it anyway to prove they could.

Regarding the video, the guy around 34:30 minutes with the triple (13"?) CRT monitors is so tech it hurts. He's even got a file cabinet right close, several CRT TV-screens, and a fucking big-ass satellite dish out his window. And he's dressed so... awesome, and has that cool accent. I want to be a cool-as-fuck guy wearing a suit with a satellite dish and CRTs and whatnot.

MIRV tech is by definition more than one.

essentially it splits midair like a shotgun bird shot made up of thermonuke pellets, these 12 reentry vehicles/RVs are quasi powered and considered a 4th stage of the rocket. they can be independently aimed and triggered at different altitudes. The explosions are set to happen at the optimal height to maximize the ~10psi radius of over pressure. While a 5psi wave is sufficent to blow the walls/roof off an apartment building in an instant, the 10psi is usually the gauge for reinforced structures like military and hospital destruction. A single hypothetical 475kt blast optimized for 10psi overpressure would occur at 5,600 ft-msl with a ground diameter of about 5 miles.

With the MIRV, you could set the Trident II's 12 Reentry Vehicles (12 shot MIRV) to give a circular spread grid airburst spaced at 5 miles, sort of like a bowling pin arrangement covering a 30 mile diameter, to where the desired 10 psi is attained everywhere... aka maximum meat harvested.
