> None of this research is necessary for bombs.

And yet that's exactly why the NIF was actually built. They do plenty of weapons research: https://wci.llnl.gov/facilities/nif I'm told the building was even built to switch over between civilian and classified use unusually quickly, but I'm having trouble turning up a citation for that right now with just my phone and 2022-Google.

> All of the difficult problems fusion power generation faces with long-term plasma confinement go away when you're just trying to squeeze as hard as you can and are willing to use fission bombs to do it in an otherwise uncontrolled manner.

Not if you want them to fit in a submarine warhead. This sort of work is not easy to do well.

You're both half-right.

The NIF is the replacement for nuclear tests. It's necessary to maintain the arsenal in a working fashion, as the warheads degrade over time and have to be replaced with new ones. https://www.npr.org/templates/story/story.php?storyId=655921...

The NIF is not for more powerful nuclear weapons, as that's entirely unnecessary. If anything, most interest these days is in less powerful weapons for potential battlefield use.

It's not the only thing they do.
